This adds the dart:_macros library to the SDK and adds support for accessing dart:_macros from package:macros. The library is not used yet.
This change is needed as a prestep to adding the package:macros and using it in the CFE and analyzer, and needs to be rolled in as the checked in sdk before package:macros can be supported.

This CL optimizes how CFE et al presubmits are run.
In the examples below we'll that it takes the presubmit time from 31+
to ~13 seconds, from 31+ to ~20 seconds and from 30+ to ~19 seconds on
a few simple cases and from 76+ to ~27 seconds in a case where files in
both _fe_analyzer_shared, front_end, frontend_server and kernel are
changed.
Before this CL, if there was changes in both front_end and
frontend_server for instance it would run one smoke-test for each.
They would each technically only test things in their own directory,
but they would do a lot of overlapping work, e.g. compiling
frontend_server also compiles front_end; the startup cost of a script
is done several times etc.
The bulk of the change in this CL is thus to only run things once.
Now, if there is a change in both front_end and frontend_server the
python presubmit will still launch a script for each, but it's just a
light-weight script that will take ~400 ms to run (on my machine) if it
decides to not do anything. What it does is that it looks at the
changed files, from that it will know which presubmits will be run and
decide which of them will actually do the work - the rest will just
exit and say "it will be tested by this other one".
Furthermore it then tries to run only the smoke tests necessary.
For instance, if you have only changed a test in front_end it will only
run the spell checker (and only for that file).
Note that this is not perfect and there can be cases where you should
get a presubmit error but wont. For instance if you remove all content
from the spellchecking dictionary file it should give you lots of
spelling mistake errors, but it won't because it won't actually run the
spell checker (as no files it should spell check was changed).
Probably you have to actively try to cheat it though, so I don't see it
as a big problem. Things will still be checked fully on the CI.
Additionally
* the generated messages will have trailing commas which speeds up
formatting of the generated files (in the cases where the
generated files will have to be checked).
* the explicit creation testing tool will do the outline of everything,
but only do the bodies of the changed files.
* building the "ast model" only compiles the outline.
Left to do:
* If only changing a single test, for instance, it will only run the
spell checker on that file, but launching the isolate its run in
still takes ~7 seconds because it loads up other stuff too. Maybe we
could have special entry points for cases where it only should run an
otherwise simple test.
* The presubmit in the sdk dir (not CFE related) doesn't do well with
many (big) changed files and testing them for formatting errors can
easily take 10+ seconds (see example below where it contributes ~5
seconds for instance). Maybe `dart format` could be made faster, or
maybe the script should test more than one file at once.

When landing https://dart-review.googlesource.com/c/sdk/+/342400
the ddc-mac builder (but not Linux and Windows) started failing.
I could reproduce on Linux though so I'm not sure why those builders
didn't fail (nor why it wasn't caught by the try bot), either way this
fixes the issues:
* Test update: E.g. a breakpoint at the end of the scope doesn't work
because it will not be inside the (wanted) scope.
* Test update: Evalating "this" now actually works.
* Scope finding update: DDC adds sourcemapping entries for the *end* of
things so e.g. the getter "c" will have offset and offset+1 added as
source mappings. When translating from javascript position to dart
position we might pick that and thus ask for the scope of offset+1,
but nothing will be found because no node has that offset.
Here I add a fall-back saying that if we get no results we ask again
for the nearest lower offset.

we'll use the new scope finder.

Previously we would encode the type of the value returned in `async`
functions as the field `futureValueType` on `FunctionNode`. For all
other kinds of functions, such as `sync`, `sync*`, and `async*`, that
field would be null. This CL renames `futureValueType` into
`emittedVAlueType`, and for functions of kinds `async`, `sync*`, and
`async*` that is expected to be the type of values emitted via
`return` or `yield` statements. For `sync` functions that field is
supposed to contain `null`.

This used to be used solely by field promotion, to recognize when a
getter arose from a declaration of an abstract field, so that abstract
fields would be promotable but explicitly declared abstract getters
would not be.
However, with the adoption of
https://github.com/dart-lang/language/issues/3328, both abstract
fields and abstract getters are now considered promotable, so there is
no longer any need to distinguish them.

This CL introduces an alternative way to calculate scopes for
expression evaluations. Currently the previous method is kept as well.
What this does is that it:
* Finds all nodes that match the offset and uri. (Ideally there's only
one, but that's not always the case --- it's the case for less than
60% of cases in the test added actually).
* Calculate the scope along the way.
* Return the scopes of all the found nodes that offset.
A test that asks for ~all file offsets in the dill files in the sdk and
compares the result with the scope the binary serialization computes is
added.
A single point can't always be found (for all dills in the sdk
only ~58.93% returns a single result), but for each query the wanted
scope is among the results returned.
For the non-outline dills in the sdk, between ~87.93% and ~94.52% of
the results are either a single result or multiple results with the
same actual scope in all of them.
Note that the test asks for ~all offsets, not just "debuggable" or
"stopable" offsets (which will likely vary depending on the vm/web
backend etc) --- likely the percentage will be higher for those points
though.
When this returns multiple results one can likely be picked by the
client based on information it has about names of variables in scope
etc.
Note that the test is rather slow, on my machine with the platforms
available there it makes 3,908,181 queries in ~3.5 minutes.
(Which corresponds to roughly 18,610 per second or under 0.06 ms per
query on average though, so it doesn't seem like a concert for actually
using it.)

The changes calls to getInterfaceTypeAsInstanceOfClass (et al.) to
getTypeAsInstanceOf to ensure that we take extension types into account.

Expressions missing offsets were:
- LogicalExpression
- ConditionalExpression
- Not
- BlockExpression
- Instantiation
- TypedefTearOff*
* I'm not sure how TypedefTearOff is actually being used, I don't see reference to it in the VM runtime. Unless the CFE lowers it before the VM gets it.
I also added a test on `binary.md` that ensures all expressions include a file offset in their serialized format. This can be expanded to statements if offsets are added to the remaining statement nodes without offsets.
TEST=Added binary_md_git_test.dart to ensure all expressions contain offset data going forward.

This flag used to be used for field promotion (to ensure that lowered
late fields are promotable, provided that they are private and final
and don't have a name that conflicts with something else
non-promotable). However, as of
https://dart-review.googlesource.com/c/sdk/+/330168, the logic for
determining when a Procedure is promotable now operates solely by
checking for all the conditions that prevent promotability. Lowered
late fields are now promotable because there is no reason for them not
to be.

This create a stub for combined member signatures from multiple
inherited non-extension type members and adds these to the
extension type declaration.
A sealed [TypeDeclaration] superclass is added to [Class] and
[ExtensionTypeDeclaration] to support accessing the enclosing type
declaration from a [Member].

This adds the representation field of an extension type declaration
as an abstract getter in the ExtensionTypeDeclaraiton marking it as
a ProcedureStubKind.RepresentationField
These are never used as interface targets and are therefore skipped
in the type flow analysis.

This adds a list of `Procedure`s to `ExtensionTypeDeclaration`. This is
meant to model representation fields and combined member signatures
computed from inherited non-extension type members.
These are not meant to be handled by the backends. The combined
member signature can be the interface target of an `InstanceInvocation`
expression but will always have a `.memberSignatureOrigin` value from
one of the original class members.
