Paul Berry 63dc645f6e Bump VM packages to language version 3.12.
This CL is part of an effort to bump the SDK requirement to `3.12.0-0`
for all the packages in `pkg` that are not published to `pub`, so that
we can get better testing of the "private named parameters" feature.

(Packages that *are* published to `pub` can't be safely bumped yet,
because SDK 3.12 hasn't been released, and I don't want to block those
packages' ability to publish useful updates to customers.)

This change covers the following packages, which are owned by
OWNERS_VM:
- pkg/dart2bytecode
- pkg/dart2native
- pkg/dtd_impl (jointly owned with OWNERS_DEVTOOLS)
- pkg/mmap
- pkg/observatory
- pkg/vm

Changes to `pubspec.yaml` files were made manually.

Changes to `.dart` files were made automatically, using `dart
fix`. Two kinds of changes were made:

- Migrate to using private named parameters where it is possible to do
  so without changing semantics. Note that this migration is
  conservative; see https://github.com/dart-lang/sdk/issues/58607 for
  details.

- Migrate to using null aware elements.

Dart Tooling Daemon

The server implementation for the Dart Tooling Daemon. This is meant to be run by our internal tooling and facilitates communication between our internal tools.

For details on the protocol used to communicate with the Dart Tooling Daemon see The DTD Protocol

Running the Dart Tooling Daemon

Compiled version

To run the tooling daemon compiled with the Dart SDK:

  1. Build the Dart SDK
  • make sure to build with create_platform_sdk
  • e.g. ./tools/build.py create_platform_sdk
  1. run dart tooling-daemon

    :info The dart binary should be the one you just built in step 1.

Testing changes locally

To quickly test changes to the tooling daemon, start it by running:

dart run bin/dtd.dart

Running tests

To run the tests under the test/ directory, run dart test test/.

However, if you are testing changes that span pkg/dtd and pkg/dtd_impl, you'll need to build the Dart SDK, and then use the built Dart executable to run the test.

  1. Build the Dart SDK: ./tools/build.py create_platform_sdk
  2. Run the test: xcodebuild/ReleaseARM64/dart-sdk/bin/dart test test/
