RFR: 8235908: omit ThreadPriorityPolicy warning when value is set from image

[David Holmes]

The changes in relation to exposing the origin of the flag as a 
JIMAGE_RESOURCE look fine. (Could potentially have been its own RFE but 
that's just bookkeeping.)

No further comment on the actual ThreadPriorityPolicy change. :)

Cheers,
David
