Since CodeSourceMaps are not serialized when non-symbolic stack traces
are enabled, use a different CSM encoding in this mode. Here, we write
out the line number as before and then the column as a separately
written integer.

The partitioning has the property that for every reference from loading unit S to unit T, either
- the reference is through a deferred prefix, or
- T is guarenteed to be loaded before S
The partitioning is constructed by cutting the dominator tree of the library import graph at deferred imports. It is suboptimal if there are deferred imports to multiple libraries in a connected component, but the expected use case involves loading units with a single deferred entry.

If the Content-Length has been set by contentLength setter, manually
setting the header to the same value will lead to the header being
dropped, since _contentLength is not updated in set() method. The method
set() will erase the header and add back the header with new value. As
_contentLength is not updated, when it adds back the new header, it
looks at _contentLength (Which is not reset) and skips the addition (
_contentLength is the same as the new value, we had the header already).

The FIDL library fuchsia.deprecatedtimezone is going away. There are
different and better ways to obtain the same functionality. This change
removes the dependency on fuchsia.deprecatedtimezone from the Dart SDK.
Adds inspect metrics that allow whitebox testing of the runners. Here's
a sample `fx iquery` excerpt from a running device, showing both a dart
and a flutter runner exposing the same OS diagnostic metrics.
```
/hub/c/dart_jit_runner.cmx/70981/out/diagnostics:
/hub/c/dart_jit_runner.cmx/70981/out/diagnostics#os:
dst_status = 0
get_profile_status = 0
timezone_content_status = 0
tz_data_close_status = 0
tz_data_status = 0

```
Under nominal operation, all of the above values should be equal to 0.
Nonzero values indicate an error.

VM calls certain functions from core libraries implicitly and in
certain cases such functions can take null as argument.
This change fixes parameters which were declared with non-nullable
types, but in fact they should take null.
These incorrectly declared parameters trigger non-null assertions in
weak mode.

- don't do it with strings passed to JS() code (they might need
to be property accesses).
- tweak thresholds, using different thresholds for slow/run-once code.

Changes:
Doing this always in precompiled mode meant increased data segment sizes
when CodeSourceMaps are stored, since encoded line/column information is
larger in the LEB-like encoding used. Now we only store column
information when we produce non-symbolic stacks, since the increased
space needed to store the columns is instead in DWARF sections and can
be stripped or elided.
Original description:
Previously, we passed line number information to the stack trace printer
and to DWARF by changing the non-special positions in the CodeSourceMap
to line numbers in precompiled mode. However, doing this lost column
information.
We get the column information back in the majority of cases by encoding
the line number and column information when neither is too large to pack
together into 30 bits. (Here, 20 bits for line and 10 bits for column.)
Otherwise, we just store the line information as before, though due to
using a bit to encode whether column info exists, it's reduced to 30
bits. If the line info is too big for that, we just return kNoSourcePos.

This hint flags code such as
int time = watch.elapsedMillisecond;
and encourages using `var` everywhere:
var time = watch.elapsedMillisecond;
Though if the type is not obvious to a developer, we should be allowed
to write it.
Furthermore it copies the rules from
`package:pedantic/analysis_options-1.9.0.yaml` to avoid being
automatically opted-in to new rules when a new package:pedantic
gets rolled into the SDK.
