x86: Add FEATURE_AVX512VP2INTERSECT and update GFNI check

Add FEATURE_AVX512VP2INTERSECT to libgcc so that enum processor_features
in libgcc matches enum processor_features in i386-builtins.c.  Update
GFNI check to support processors with SSE and AVX versions of GFNI.

	PR target/95212
	PR target/95220
	* config/i386/cpuinfo.c (get_available_features): Fix
	FEATURE_GFNI check.  Also check FEATURE_AVX512VP2INTERSECT.
	* config/i386/cpuinfo.h (processor_features): Add
	FEATURE_AVX512VP2INTERSECT.
