8266957: SA has not followed JDK-8220587 and JDK-8224965

[YaSuenag]

Following jtreg tests for SA would fail because SA has not followed JDK-8220587 and JDK-8224965.

• serviceability/sa/ClhsdbDumpheap.java
• serviceability/sa/ClhsdbFindPC.java
• serviceability/sa/ClhsdbInspect.java
• serviceability/sa/ClhsdbSymbol.java
• serviceability/sa/TestHeapDumpForInvokeDynamic.java
• serviceability/sa/TestJmapCore.java
• serviceability/sa/TestJmapCoreMetaspace.java

They need to handle relocated objects and/or live regions (pages). SA should handle them.

This change passes serviceability/sa jtreg tests on Linux x64 with -vmoption:-XX:+UseZGC, but I want to know this change works fine on testbed for ZGC in Oracle. Could you help?

Ping: could you review this change?
I know this is too big to review, so it is also welcome to comment to divide this PR.

This PR would fix JDK-8267045 which is marked as P3. If we can mark P3 to this PR, we can get more time to review.
I think SA should support ZGC as possible in next major release.

Thanks @plummercj for the review!
May I get the review from ZGC folks?

May I get the review from ZGC folks?

The ZGC team won't be doing SA code reviews. I'll have someone else from the svc team do a second review, but keep in mind these reviews are primarily just to make sure the changes won't break anything (other than SA support for ZGC).
