RFR: 8257820: Remove gc/ergonomics/TestMinHeapSize.java as it is too brittle

[Thomas Schatzl]

Hi all,

  can I have reviews for this change that removes the gc/ergonomics/TestMinHeapSize.java test?

We found that it is unstable, and with reasonable effort very likely can't be made to work: we have no idea how much (C heap) memory the rest of the VM will use, or will in the future, so there will likely always be a constant need to update it. Even during review there have already some adaptations to make it work, until it "worked", but then it intermittently started failing in CI anyway.

Testing: this is a trivial removal of a complete test/file.

Thanks,
  Thomas
