arm64: alternatives: use cpucap naming

To more clearly align the various users of the cpucap enumeration, this patch
changes the alternative code to use the term `cpucap` in favour of `feature`.
The alternative_has_feature_{likely,unlikely}() functions are renamed to
alternative_has_cap_<likely,unlikely}() to more clearly align with the
cpus_have_{const_,}cap() helpers.

At the same time remove the stale comment referring to the "ARM64_CB
bit", which is evidently a typo for ARM64_CB_PATCH, which was removed in
commit:

  4c0bd995d73ed889 ("arm64: alternatives: have callbacks take a cap")

There should be no functional change as a result of this patch; this is
purely a renaming exercise.
