arm64: unify native/compat instruction skipping
Skipping of an instruction on AArch32 works a bit differently from
AArch64, mainly due to the different CPSR/PSTATE semantics.
Currently arm64_skip_faulting_instruction() is only suitable for
AArch64, and arm64_compat_skip_faulting_instruction() handles the IT
state machine but is local to traps.c.
Since manual instruction skipping implies a trap, it's a relatively
slow path.
So, make arm64_skip_faulting_instruction() handle both compat and
native, and get rid of the arm64_compat_skip_faulting_instruction()
special case.
