RFR(XS) 8069021: Exclude compiler/codecache/stress tests from JPRT runs

[Vladimir Kozlov]

New codecache stress tests added by 8059551 added 45 min to 
hotspot_compiler_2 execution time. I got my job killed because total 
execution of it took > 1 hour.

Fix tested in JPRT.

I filed separate bug to investigate long execution time:

Thanks,
