Carlo Bernaschina ba36008af6 Add --trace-skia parameter to flutter run (#12070)
* Add --trace-skia parameter to flutter run

Skia tracing is extremely useful for internal debug, but reduces the
amount of space available in the Dart Timeline buffers.
Disable skia tracing by default and expose them via the --trace-skia
flag.

Dart SDK dependency

The Dart SDK is downloaded from one of the supported channels, cached in bin/cache/dart-sdk and is used to run Flutter Dart code.

The file bin/internal/dart-sdk.version determines the version of Dart SDK that will be downloaded. Normally it points to the dev channel (for example, 1.24.0-dev.6.7), but it can also point to particular bleeding edge build of Dart (for example, hash/c0617d20158955d99d6447036237fe2639ba088c).
