x86emul: support ENQCMD insns

Note that the ISA extensions document revision 038 doesn't specify
exception behavior for ModRM.mod == 0b11; assuming #UD here.

No tests are being added to the harness - this would be quite hard,
we can't just issue the insns against RAM. Their similarity with
MOVDIR64B should have the test case there be god enough to cover any
fundamental flaws.
