SIMD: Remove unused (and unlikely to be ever used) AVX-512 profiles
"AVX512MIC" (Many Integrated Cores) is the set of AVX-512 features found
on the Intel Xeon Phi coprocessors (codename "Knights Landing"), which
is an unlikely architecture for Qt to run on.
The two profiles with VL came from study of early GCC code and are no
longer applicable. GCC source code now shows both VBMI and IFMA as part
of the -march=cannonlake feature set.
