RFR: 8336754: Remodel TypeAnnotation to "has" instead of "be" an Annotation

[Chen Liang]

`TypeAnnotation` is not an annotation, as it should not be used in places like `AnnotationValue.ofAnnotation`. Thus it's remodeled to contain an annotation at a given location instead of to be an annotation.

Depends on #20205.
