x86/fpu/xstate: Define new macros for supervisor and user xstates
XCNTXT_MASK is 'all supported xfeatures' before introducing supervisor
xstates. Rename it to XFEATURE_MASK_USER_SUPPORTED to make clear that
these are user xstates.
Replace XFEATURE_MASK_SUPERVISOR with the following:
- XFEATURE_MASK_SUPERVISOR_SUPPORTED: Currently nothing. ENQCMD and
Control-flow Enforcement Technology (CET) will be introduced in separate
series.
- XFEATURE_MASK_SUPERVISOR_UNSUPPORTED: Currently only Processor Trace.
- XFEATURE_MASK_SUPERVISOR_ALL: the combination of above.
