implement AVX-512 second FMA detection

This uses the CPUID processor name.

We use the condensed method developed for Google cpu_features:
https://github.com/jeffhammond/cpu_features/blob/avx512_fma_count/src/cpuinfo_x86.c#L119
(this link will expire when it is merged into the upstream project)

A more pedantic approach is shown here:
https://github.com/jeffhammond/vpu-count/blob/master/vpu-count.c

This code must be updated when new Intel processors are released.
The author of this commit will bear that maintenance burden as long as possible.
