RFR: 8258908: Remove JVM option CleanChunkPoolAsync

Tue Jan 5 22:02:12 UTC 2021

Please review this small change to remove JVM develop option CleanChunkPoolAsync.  The option was originally added for embedded builds so they could clean chunk pools synchronouosly.

The change was tested with Mach5 tiers 1-2 on Linux, Mac OS, and Windows, and tiers 3-5 on Linux x64.

Thanks, Harold
