RFR: 8311084: Add typeSymbol() API for applicable constant pool entries [v2]

[Chen Liang]

> 5 Constant Pool entries, namely ConstantDynamicEntry, InvokeDynamicEntry, FieldRefEntry, MethodRefEntry, and InterfaceMethodRefEntry should have a typeSymbol() API to return the nominal/symbolic descriptor (ClassDesc or MethodTypeDesc).
> 
> This API is not added to NameAndTypeEntry itself, for a NameAndTypeEntry only knows if its type should be a field or method type from the other entries that refer to it.
> 
> This is one of the issues discussed in this mailing list thread: https://mail.openjdk.org/pipermail/classfile-api-dev/2023-June/000381.html
