aarch64: Add support for Armv9.1-A to Armv9.3-A

This patch adds AArch64 support for -march=armv9.[123]-a.
The behaviour of the new options can be expressed using a
combination of existing feature flags, so we don't need to
eat into the vanishing number of spare AARCH64_FEATURE_* bits.
Hoewver, it was more convenient to separate out the |s of
feature flags so that Armv9.1-A could reuse the set for
Armv8.6-A, and so on.
