[AArch64] Correct position of CFI Instruction for Pointer Authentication (#137795)

This reverts partially this commit
0b73b5af60f2c544892b9dd68b4fa43eeff52fc1.
This is not a clear revert because other changes already landed.
CFI directives like `.cfi_negate_ra_state` must be emitted after the
instruction.
If the execution is stopped before the `paciasp` instruction is executed
the debugger/unwinder would try to authenticated the return address as
the `.cfi_negate_ra_state` already indicates it got signed.
