[parser] Parse and skip metadata according to spec Make the parser handle metadata properly according to the spec. There has been some confusion in regards to metadata because https://github.com/dart-lang/language/blob/master/accepted/future-releases/small-features-21Q1/feature-specification.md (used to) say we needed a spec update. That was done in the parser in https://dart-review.googlesource.com/c/sdk/+/182668 but really that made the parser adhere to the spec as it was which is also correct (as the spec change wasn't needed at all). The parser also needs to be able to skip metadata, though, and that wasn't done it that CL which caused the issues in https://github.com/dart-lang/sdk/issues/45120 The work directly in this CL is: * Add lots of comments to parseMetadata to make them more up-to-date with the spec. * Fix skipMetadata to correspond to parseMetadata. * Tests verifying that 45120 is fixed in the parser and that metadata in general works as expected in the parser. (In working on this, the future specification was corrected to say that the spec did not need updating. Thanks to Erik for the quick turn-around there).

Dart is:
Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.
Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.
Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
Dart is free and open source.
