RFR: 8339307: jhsdb jstack could not trace FFM upcall frame

[Yasumasa Suenaga]

This PR is successor of #20789 . I got some comments in there, then I needed to fix in many pooints. And also I have to fix branch name to kick GHA automatically (#20789 is named with `pr/`, it meets the condition to skip GHA). Hence I've opened another PR for this JBS issue.

This PR has been updated with about topics since #20789:
* Use `JavaFrameAnchor` instead of raw frame pointer to unwind frame of `UpcallStub`.
* The change happens x86 (includes AMD64), aarch64, PPC64, RISC-V 64 only - s390 is out of scope because SA does not have s390 implementation.
    * Only both AMD64 and aarch64 have tested on GHA.
* Refactor testcase to meet expected condition certainly.
