x86: make AES/PCMULQDQ respectively prereqs of VAES/VPCMULQDQ
These probably should have been put in place already anyway, but they're
very much wanted in order to then put AVX10.1 support on top. Note that
to avoid reverse dependencies towards SSE (just like we already do for
AVX and XOP), add_isa_dependencies() needs some further tweaking.
While there also address a related anomaly: Disabling AES but neither
AVX nor VAES (similarly for {,V}PCLMULQDQ) would better keep the 128-bit
VEX-encoded forms available. Note that for this the VAES insns are moved
past the AVX+AES ones, to avoid the property-11 test suddenly failing.
The test really is wrong, but let's not also make things inconsistent:
Without the movement, YMM use would be correctly recorded for the
128-bit forms simply because the first template already matches, as long
as VAES wasn't disabled. Yet it still wouldn't be if only AVX+AES were
enabled. Nor would behavior here then be the same as for VPCLMUL* insns.
