build-sys: meson: Check if cpuid.h header is usable

Browse Source 
With clang compiler including cpuid.h will produce error if architecture is not
x86-based, and cheching if cpuid.h exists via Meson has_header() is not enough.

Fix this by creating a list of headers checked to be usable via Meson
check_header() function, and move cpuid.h to that list.
