tunes/arm: add support for newer arm64 cores

Add tunes for cores that have been present since GCC 14.1.0.
These have been present in meta-arm since mid-July, and have all been
verified with fvp-base and testimage.  Of those present in meta-arm,
arch-armv8-9a.inc, arch-armv9-4a.inc, and arch-armv9-5a.inc have been
excluded from this commit, as there are currently issues compiling some
packages (but still present in meta-arm for those that want to use them
despite those issues).
