  As was recently done for hwcaps convert all the cpufeatures that match
on ID registers to use helper macros to initialise all the data fields
that the matching code uses.  The feature table is much less of an eye
chart than the hwcap tables were so the benefits are less substantial
but the result is still less verbose and error prone so still seems like
a win.

Changes in v2:
- Re-add missed .matches in WFxT.
- Rebase onto v6.3-rc3.
- Link to v1: https://lore.kernel.org/r/20230303-arm64-cpufeature-helpers-v1-0-b16cf36acaea@kernel.org
