Drop XC_FEATUREMASK_DEEP_FEATURES. It isn't used by any callers, and unlike
the other static masks, won't be of interest to anyone without other pieces of
cpuid-autogen.h
In xc_get_static_cpu_featuremask(), use a 2d array instead of individually
named variables, and drop the switch statement completely.
No practical change.
