8281585: Remove unused imports under test/lib and jtreg/gc

[GoeLin]

I backport this for parity with 17.0.11-oracle.

Some simple resolves were needed:
test/hotspot/jtreg/gc/arguments/TestArrayAllocatorMallocLimit.java
Copyright.

test/hotspot/jtreg/gc/arguments/TestG1HeapRegionSize.java
Resolved import.

test/hotspot/jtreg/gc/arguments/TestG1RemSetFlags.java
Not in 17.

test/hotspot/jtreg/gc/arguments/TestVerifyBeforeAndAfterGCFlags.java
Copyright and imports due to context.

test/hotspot/jtreg/gc/g1/TestEvacuationFailure.java
Test not in 17.

test/hotspot/jtreg/gc/g1/TestSkipRebuildRemsetPhase.java
Resulved imports due to differences in context.

test/lib/jdk/test/lib/hprof/model/JavaValueArray.java
