x86: Rename {domctl,sysctl}.cpu_policy.{cpuid,msr}_policy fields
These weren't great names to begin with, and using {leaves,msrs} matches up
better with the existing nr_{leaves,msr} parameters anyway.
Furthermore, by renaming these fields we can get away with using some
#define
trickery to avoid the struct {cpuid,msr}_policy merge needing to happen in a
single changeset.
No functional change.
