Now that there's only one implementation of TypeConstraintGatherer, it
can be merged with the abstract class.

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.

Analyzer fix https://github.com/dart-lang/sdk/issues/54754 has
landed. A new version of package:analyzer and package:dartdoc have
been released. `pub global activate dartdoc` should now work.
Patchset 1 is identical to the original CL.
The only difference is an extra test testing with negative offsets.
=== Original CL description ===
Structs and unions can now be created from an existing typed data
with the new `create` methods.
The typed data argument to these `create` methods is optional. If
the typed data argument is omitted, a new typed data of the right
size will be allocated.
Compound field reads and writes are unchecked. (These are
TypedDataBase loads and stores, rather than TypedData loads and stores.
And Pointers have no byte length.) Therefore the `create` method taking
existing TypedData objects check whether the length in bytes it at
least the size of the compound.

Often when rebasing I get conflicts in
pkg/_fe_analyzer_shared/lib/src/messages/codes_generated.dart
which is a generated file. This should generally be fine,
because I can just regenerate it.
Except that the code regenerating it uses the very file,
so I can't run it.
Until now I've had to revert the changes in the file and then run the
generate script.
This CL adds a "failsafe" version that doesn't use the file,
but doesn't directly format it either, then calls the original script
which will also format it.
Call with something like
```
out/ReleaseX64/dart pkg/front_end/tool/_fasta/generate_messages_failsafe.dart
```

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.
*Example runs before and after*:

* We use `isAugmenting` instead of `isPatch` to
mark that the origin of a builder is not the builder itself.
* We use `isPatchLibrary` on `SourceLibraryBuilder`s created as patches

* We use `isAugmentation` on `SourceClassBuilder`s and

Closes https://github.com/dart-lang/sdk/issues/54138
Adds a helper to do better type-checks so that users don't
accidentally using is checks or have to manually do the right
typeof or instanceof checks. In order to do this, there is
some refactoring to make ExportCreator a SharedInteropTransformer
(as it's shared across all backends) so that we can reuse an
existing visitor. In the same class, we remove unnecessary setting
of parent pointers. We should clean up the fileOffsets as well,
but dart2js verifies that those are set, so we keep them as is
for now. Also adds some static errors for edge cases.

This is generally useful for users working around some limitations of
dart:html. While we want to encourage users to use package:web,
dart:html is not available on dart2wasm and users can use dart:html in
other ways already e.g. in an interop extension type, so it doesn't make
sense to disallow this. We also allow type parameters that extend these
types as well.
In order to make this a bit more performant (subtyping checks may be
expensive), code is refactored to cache more readily and separate the
notion of an allowed representation type vs interop extension type. We
also define the notion of a "core" interop type, which will be useful
when we want to efficiently query what interop type users are using
underneath the possible layers of extension types.
A few missing tests around typed_data are added and the error around
invalid types is reworded to include this change and be more consise.

The front end and analyzer use the same representation for types and
type schemas, with the unknown type schema (`_`) treated as a
pseudo-type. This creates the risk of accidentally mixing types and
schemas, resulting in `_` accidentally "leaking" into the type system
and showing up in static analysis results or error messages.
As a step toward reducing this risk, this change adds a type parameter
to `TypeAnalyzer`, preventing the shared type analysis code from being
able to assume that types and schemas are represented the same. This
extra discipline makes it much easier to search through the code and
identify how types are manipulated vs. how type schemas are
manipulated, and makes it impossible for the shared type analysis to
accidentally leak `_` into the type system.
I believe this change will also make it easier to implement some type
inference improvements we've been contemplating, such as improved type
inference of `.map(...).toList()`, as well as
https://github.com/dart-lang/language/issues/3471, because those
improvements may require introducing new kinds of type schemas.

Both `sizeOf` and `AllocatorAlloc.call` use the new type as bound.
This prevents runtime errors on trying to call these two static
methods with unsized native types. All tests testing for these runtime
errors have been deleted.
The `NativeTypes` implementing `SizedNativeType` are as follows:
* The native integer types, `Float`, and `Double`.
* `AbiSpecificInteger` and it's subtypes.
* `Struct` and `Union` and their subtypes. The
The `NativeTypes` not implementing `SizedNativeType` are as follows:
* `Void` has no size.
* `Opaque` and subtypes have unknown size.
* `Handle` is considered opaque. Cannot be used as field in compounds.
* `Array` does not carry a size in its type. Can be used as fields in
compounds with an annotation specifying the size.
* `NativeFunction` is considered opaque. Would have variable size.
* `VarArgs` is only a marker in function signatures.
`Struct`s and `Union`s can have only `SizedNativeType`s and `Array`s
as fields. Documentation for these is in flux in another CL, so we
should update it there.
This CL also replaces a bunch of `extends NativeType` with
`implements` clauses and made `NativeType` itself `abstract`.
