Adds logic to pass `--include-unsupported-platform-library-stubs` to the CFE when launched via `flutter widget-preview start`, as well as logic to ensure the flag can't be passed as an extra frontend option to bypass compile time errors due to imports of unsupported libraries. Fixes flutter#166431

Code Review
This pull request adds support for dart:ffi imports in the widget preview feature by passing the --include-unsupported-platform-library-stubs flag to the Dart frontend compiler (CFE) for the dartdevc target.
The changes include:
- Updating the
BUILD.gnfile to pass the flag when building the web SDK's DDC platform summary. - Adding an
includeUnsupportedPlatformLibraryStubsflag toBuildInfoand passing it to theResidentCompiler. - Enabling this flag for the
widget-preview startcommand. - Adding safeguards to filter this flag from user-provided
extraFrontEndOptionsand restricting its use to thedartdevctarget model. - Adding tests to verify the new logic and safeguards.
The changes appear to correctly implement the intended feature and include measures to prevent misuse. I have one suggestion to make the error message in compile.dart more general for future maintainability.
