x86: relax mask register constraints

While their use for masking is indeed restricted to %k1...%k7, use as
"normal" insn operands also permits %k0. Remove the unnecessary
limitations, requiring quite a few testsuite adjustments.

Oddly enough some AVX512{F,DQ} test cases already check for %k[0-7],
while others did permit {%k0} - where they get touched here anyway this
gets fixed at the same time.
