Adds support for --bundle-sksl-path to windows, linux, macOS, and iOS.

Fixes #53115

Instead of targets/dart.dart -> targets/common.dart

Also combines experiments into extraGenSnapshot/ExtraFrontEndOptions. Allows providing --no-sound-null-safety to allow out of order migration and running.

Ensure iOS and android builds can be correctly cached. Use the performance-measurement-file to verify that all targets were skipped on the second invocation. This is only run on the flutter_gallery build.
