[jdk11u-dev] RFR: 8220813: update hotspot tier1_gc tests depending on GC to use @requires vm.gc.X

[Goetz Lindenmaier]

I backport this for parity with 11.0.16-oracle.

I had to resolve quite some files, mostly because "8214799: Add package declaration to each JTREG test case in the gc folder" Is not in 11.
I looked at backporting that chagne. It would simplify backporting gc test changes, but requires a lot of work itself. So I decided to resolve this change.

TestMetaSpaceLog.java is not in 11, so I skipped the changes to that file.
