RFR: 8160088: update hotspot tests depending on GC to use @requires vm.gc.X

[Michail Chernov]

Copyrights for some tests were not updated ( for example - 
test/runtime/SharedArchiveFile/SharedStringsRunAuto.java) , please 
update it before pushing. I don`t need additional review for it.

Thanks,
Michail.
