Enable AMX(TMUL) for Sapphire Rapids

This is the first draft of the commits which are required to support AMX (aka TMUL) on SPR. I suspect there are some missing commits.

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2004190
Tested: Intel to perform initial testing.

v2: added missing upstream commits 21e96a2035db and 52d0b8b18776
