[jdk17u-dev] RFR: 8280705: Parallel: Full gc mark stack draining should prefer to make work available to other threads

[Aleksey Shipilev]

Clean backport to match what G1 is also doing. The change was in mainline for more than a year without related issues.

Additional testing:
 - [ ] Linux x86_64 fastdebug `tier1` with `-XX:+UseParallelGC`
 - [ ] Linux x86_64 fastdebug `tier2` with `-XX:+UseParallelGC`
 - [ ] Linux x86_64 fastdebug `tier3` with `-XX:+UseParallelGC`
