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

[Vladimir Kozlov]

I changed mailing list to wider audience.

Note for reviews, Java SE builds and products are not affected by this change.

This change affects only GraalVM which sets ThreadPriorityPolicy=1 by default in their build.
GraalVM release notes have statement about that to notify GraalVM users because it may affect applications performance.

RFE describes why GraalVM needs that.

Change looks good to me.

Thanks,
Vladimir K
