  [AArch64] Make apple-m4 armv8.7-a again (from armv9.2-a).  (#106312)

This is a partial revert of c66e1d6f3429.  Even though that
allowed us to declare v9.2-a support without picking up SVE2
in both the backend and the driver, the frontend itself still
enabled SVE via the arch version's default extensions.

Avoid that by reverting back to v8.7-a while we look into
longer-term solutions.

(cherry picked from commit e5e38ddf1b8043324175868831da21e941c00aff)
