Resolve `CONSTANT_MethodRef` entries during CDS dump time to improve start-up performance.

- This PR uses the same framework introduced in #19355 and just added handling for methods.
- More filtering is needed when building the default archive in the JDK: constant pool resolution when running the `build.tools.classlist.HelloClasslist` program is not deterministic (due to concurrency in core library classes). This could cause different values in the `@cp` lines in the classlist file. The benefit of pre-resolved constant pool entries is more visible for custom archives and not so much for the default archive in the JDK, so we disable this optimization for the default CDS archive, until we can find a way to make it deterministic.
