This CL implements `NativeFinalizer` in the GC.
`FinalizerEntry`s are extended to track `external_size` and in which
`Heap::Space` the finalizable value is.
On attaching a native finalizer, the external size is added to the
relevant heap. When the finalizable value is promoted from new to old
space, the external size is promoted as well. And when a native
finalizer is run or is detached, the external size is removed from the
relevant heap again.
In contrast to Dart `Finalizer`s, `NativeFinalizer`s are run on isolate
shutdown.
When the `NativeFinalizer`s themselves are collected, the finalizers are
not run. Users should stick the native finalizer in a global variable to
ensure finalization. We will revisit this design when we add send and
exit support, because there is a design space to explore what to do in
that case. This current solution promises the least to users.
In this implementation native finalizers have a Dart entry to clean up
the entries from the `all_entries` field of the finalizer. We should
consider using another data structure that avoids the need for this Dart
entry. See the TODO left in the code.

Previously, this field existed as a sanity check to help ensure that
the client didn't accidentally call `functionExpression_end` more
often than `functionExpression_begin`. However now that flow analysis
maintains an explicit stack of what constructs have been begun and not
ended, the check is redundant, because trying to pop from an empty
stack would cause a runtime failure anyway.

The old code tries to determine something by using a forwarding listener
without forwarding to anything. It leaked a rewrite though, meaning that
the rewrite stayed, but the error given when rewriting wasn't passed on.
When then parsing it with the real listener, the rewrite was in effect
and there was no error to report. In total no errors were reported.
This fixes the issue by undoing any rewrites in this situation.

This adds direct support for class member augmentation, including checks
that the 'augment' modifier is used correctly. Different from the patch
member support, non-augment members added in augment classes are now
part of the interface of the class and can therefore be used outside
the augmentation library.
The CL includes support for using the 'import augment' syntax to import
libraries as augmentation libraries. The enable direct testing of the
augmentation features in expectation tests.

This changes the way the 'augment' modifier is handled in the parser.
Instead of being special cased for class declarations, it is now a
built-in identifier recognized only when the scanner is configured to
support augmentation libraries.
The change supports the used of the 'augment' modifier on not only
class declarations but also mixin and member declarations, as needed
for supporting macros.

has been refactored to support that Phase 1 can apply all macro
applications within a library in bulk, but Phase 2 can apply each
macro application in sequence.
The later is to prepare for making added member visible to subsequent

- Refactors pretty heavily the isolate executor code such that it can be reused.
- Refactors the isolated executor test into a shared test for all executors
- Removes the mirror based executor entirely - I don't see a path forward with this one.

This adds support for the generating a synthesized augmentation
library for each library in which phase 1 macros were applied.
Current implementation piggybacks on the patch library support. The
intension is that both patches and augmentations are handled through
the same general mechanism. For now, the wording refers to augmentation
libraries as patch libraries where the implementation is shared.
Testing is extended to verify that the generated classes are
included in the resulting AST.
