8389293: Remove developer flag -XX:ArchiveHeapTestClass

[iklam]

This is just a draft.

• Removed ArchiveHeapTestClass
• Replaced most usage with AOTInitTestClass
• The code that uses ArchiveHeapTestClass in ArchivedIntegerCacheTest isn't useful anymore. I deleted it.

I will create a real PR to integrate this into the JDK mainline, after JEP 401 integration.

This PR contains a fix for JDK-8389233, which should be fixed before this PR proceeds.
