Add resolve-type-names: false magic comment

PR: #2234

You can add resolve-type-names: false magic comment at the beginning of RBS files to skip type name resolution. This makes RBS file loading faster, typically for generated RBS files where the type names can be identified already.

# resolve-type-names: false

class Foo
  def foo: () -> ::String         # ::String should be used instead of String
end

Annotations on constants, globals, class/module aliases

PR: #2302

Constant declarations, global declarations, and class/module alias declarations can be annotated.
