Support coloring the identifier part of an annotation the same as the annotation @ marker

Problem

I’m always frustrated to see that while the semantic token type for annotations should be annotation but :

1. The semantic token type for annotations override and required is currently set as property.
2. The semantic token type for annotation Deprecated is currently set as class.

Due to the above problem one can’t assign distinct colors to properties and annotations.

Solution I’d like

Please set the semantic token type as annotation for all annotations including but not limited to Deprecated, override and required .

According to official docs , any class can be transformed into an annotation, as long as they provide a const constructor and since annotations are prefixed by @ so they are easy to be recognized and assigned the semantic token type as annotation.

Note: Since the tokens come from the language server, if/when merged, it will require an SDK update before it shows up in VS Code (not a VS Code extension update).

I’ve a change open to add a modifier here:

https://dart-review.googlesource.com/c/sdk/+/217940/

This allows you to customise how the identifier part of the annotation looks (either to be the same as the annotation marker/parens or separately) like this:

"editor.semanticTokenColorCustomizations": {
	"rules": {
		"annotation": "#00ff00",
		"*.annotation": "#00ff00",
	},
},

Which looks like the following:

Note: Only the identifier part is covered, so nested expressions/identifiers will be colour normally.
