  [AArch64] Remove apple-a7-sysreg. (#102709)

This feature provided CPM_IOACC_CTL_EL3, a lone system register that has
been carried over since the original ARM64 implementation, where it was
the only processor-specific register in a long list of architectural
sysregs. We don't need it here.

It's been used as a generic processor-specific sysreg in tests, but the
functionality they target is now better covered in other more exhaustive
tests.
