Summary
-------
Update specifications in `AnnotationConstantValueEntry` and `AnnotationValue.OfConstant`, and rename `AnnotationValue.OfInteger` and `OfCharacter` to `AnnotationValue.OfInt` and `AnnotationValue.OfChar`.
Problem
-------
`AnnotationConstantValueEntry` and `AnnotationValue.OfConstant` are old modeling APIs before [specific types of annotation values are added](https://github.com/openjdk/jdk-sandbox/commit/bb7e29474ecfcfbd1eb01d237593eb80d062944f). Their designs do not account for their presence.
`AnnotationValue.OfConstant` is bug-prone: for example, `ConstantDesc constantValue()` method returns an `Integer` for char values, which is misleading because users may think that it returns a correct `Character` Object suitable for `AnnotationValue::of` to restore the annotation value, or for `toString` printing. This is already manifest in ClassFile API's `ClassPrinter`.
`AnnotationValue.OfInteger` and `OfCharacter` have weird naming; their factories are `ofInt` and `ofChar`, tag constants `AEV_INT` and `AEV_CHAR`, value accessors `intValue` and `charValue`.
`AnnotationValue` as a whole lacks documentation and would benefit from the addition of documentation.
Solution
--------
Update AnnotationValue.OfConstant and AnnotationConstantValueEntry specifications, to emphasize the difference between VM types and the language types (namely subint are represented as int). `OfConstant` additionally has accessors for the VM (as CP entries) vs language types (as live objects), with clarifications on the methods.
`ConstantPoolBuilder::annotationConstantValueEntry` is removed. It had no usage.
The `AnnotationConstantValueEntry constant()` is now specific to each value subtype. Users are supposed to access the entry with pattern matching in switch.
`AnnotationValue.OfInteger` and `OfCharacter` are renamed to `OfInt` and `OfChar`.
Vastly improve the specification for AnnotationValue.
