x86/cpu: Shorten CPU matching macro

x86/cpu: Shorten CPU matching macro

To add cpu-type to the existing CPU matching infrastructure, the base macro
X86_MATCH_VENDOR_FAM_MODEL_STEPPINGS_FEATURE need to append _CPU_TYPE. This
makes an already long name longer, and somewhat incomprehensible.

To avoid this, rename the base macro to X86_MATCH_CPU. The macro name
doesn't need to explicitly tell everything that it matches. The arguments
to the macro already hint at that.

For consistency, use this base macro to define X86_MATCH_VFM and friends.

Remove unused X86_MATCH_VENDOR_FAM_MODEL_FEATURE while at it.
