RFR: 8332936: Test vmTestbase/metaspace/gc/watermark_70_80/TestDescription.java fails with no GC's recorded

[Thomas Schatzl]

Hi all,

  please review this change to exclude the watermark tests from use with -Xcomp.

The failures reported are related to -Xcomp triggering the wrong kind of garbage collection pauses (CodeCache related GCs instead of Metadata related GCs) the test then fails on.

The proposed solution is to just disable the tests with -Xcomp: the tests are not related to compilation at all.

Testing: local, gha

Thanks,
  Thomas
