RFR: 8293979: Resolve JVM_CONSTANT_Class references at CDS dump time

[Ioi Lam]

Some `JVM_CONSTANT_Class` entries are guaranteed to resolve to the same value at both CDS dump time and run time:

- Classes that are resolved during `vmClasses::resolve_all()`. These classes cannot be replaced by JVMTI agents at run time.
- Supertypes -- at run time, a class `C` can be loaded from the CDS archive only if all of `C`'s super types are also loaded from the CDS archive. Therefore, we know that a `JVM_CONSTANT_Class` reference to a supertype of `C` must resolved to the same value at both CDS dump time and run time.

By doing the resolution at dump time, we can speed up run time start-up by a little bit.

The `ClassPrelinker` class added by this PR will also be used in future REFs for pre-resolving other constant pool entries. The ultimate goal is to resolve `invokedynamic` and `invokehandle` so we can significantly improve the start-up time of features such as Lambda expressions and String concatenation.
