build : improve disabling AVX-512 (#2129)

Browse Source 
* cmake : make WHISPER_NO_AVX512=ON disable all subsets of AVX-512

Previously it happened only for MSVC, but it makes sense to have the
same behavior for other compilers too.

* make : reorder x86 ISA extensions in chronological order

And update compiler flags at the end to ease modifying conditions.

* make : support WHISPER_NO_AVX512=1 for disabling all AVX-512 subsets.

That way you do not have to override each AVX-512 subset setting
individually if it has been turned on during autodetection.
