[jdk17u-dev] RFR: 8332252: Clean up vmTestbase/vm/share

[Goetz Lindenmaier]

I backport this for parity with 17.0.17-oracle.

I had to touch three files:

test/hotspot/jtreg/vmTestbase/metaspace/gc/HighWaterMarkTest.java
Resolved Copyright because "8284853: Fix various 'expected' typo" is not in 17.


test/hotspot/jtreg/vmTestbase/metaspace/staticReferences/StaticReferences.java
Resolved imports because later change "8202100: Merge vm/share/InMemoryJavaCompiler w/ jdk/test/lib/compiler/InMemoryJavaCompiler" was already backported.

test/hotspot/jtreg/vmTestbase/vm/share/ProcessUtils.cpp
Several changes are missing here. These are all cleanups that touch code that is removed anyways.
Resolved.

I ran the modified tests. Where a aux file has been modified, I selected some test that uses the coding as assured it is passing.
