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.

Package validation

The packages in pkg/ are automatically validated on the LUCI CI bots. The validation is largely done by the tools/package_deps package; it can be tested locally via:

dart tools/package_deps/bin/package_deps.dart

Packages which are published

There are several packages developed in pkg/ which are published to pub. Validation of these packages is particularly important because the pub tools are not used for these packages during development; we get our dependency versions from the DEPS file. It's very easy for the dependencies specified in a package's pubspec file to get out of date wrt the packages and versions actually used.

In order to better ensure we're publishing correct packages, we validate some properties of the pubspec files on our CI system. These validations include:

  • that the dependencies listed in the pubspec are used in the package
  • that all the packages used by the source are listed in the pubspec
  • that we don't use relative path deps to pkg/ or third_party/ packages

Packages which are not published

For packages in pkg/ which we do not intend to be published, we put the following comment in the pubspec.yaml file:

# This package is not intended for consumption on pub.dev. DO NOT publish.
publish_to: none

These pubspecs are still validated by the package validation tool. The contents are more informational as the pubspecs for these packages are not consumed by the pub tool or ecosystem.

We validate:

  • that the dependencies listed in the pubspec are used in the package
  • that all the packages used by the source are listed in the pubspec
  • that a reference to a pkg/ package is done via a relative path dependency

Adding new packages

Run gclient sync to re-generate .dart_tool/package_config.json after adding a new package.

Testing packages

Currently dart test can't be used to run the tests, use test.py as usual. E.g. the command ./tools/test.py -n...<path> runs all tests with prefix <path>.
