[jdk25u-dev] RFR: 8212084: G1: Implement UseGCOverheadLimit

[Goetz Lindenmaier]

I backport this for parity with 25.0.3-oracle.

src/hotspot/share/gc/g1/g1CollectedHeap.cpp
Deleting two blocks failed. The code is not in 25. It came by "8366865: Allocation GC Pauses Triggered after JVM has started shutdown". The original change just moved this code.  I omit adding it in the new location, too.

src/hotspot/share/gc/parallel/parallelArguments.cpp
Deleting one block failed. The code is not in 25.

src/hotspot/share/gc/parallel/parallelScavengeHeap.cpp
Omitted two patches that make only sense with "8338977: Parallel: Improve heap resizing heuristics"

src/hotspot/share/gc/parallel/parallelScavengeHeap.hpp
Omitted one patch that makes only sense with "8338977: Parallel: Improve heap resizing heuristics"

Compilation stumbles, as long_term_gc_time_ratio() is not available in 25.
This was introduced by "8359348: G1: Improve cpu usage measurements for heap sizing".
I replace it by it's predecessor method long_term_pause_time_ratio().
I also need a new include to make it compile. See second commit.

The new test runs with G1 and parallel GC.
As "8338977: Parallel: Improve heap resizing heuristics" is not in 25 and
I omitted the patches for parallelScavengeHeap.cpp form this change,
the test does not work.  I disabled it.  See third commit.
