target/arm: Update user-mode ID reg mask values

For user-only mode we reveal a subset of the AArch64 ID registers
to the guest, to emulate the kernel's trap-and-emulate-ID-regs
handling. Update the feature bit masks to match upstream kernel
commit a48fa7efaf1161c1c.

None of these features are yet implemented by QEMU, so this
doesn't yet have a behavioural change, but implementation of
FEAT_MOPS and FEAT_HBC is imminent.
