[AArch64] Fix the emission of WinCFI for pac-ret+leaf and SCS (#147518)
This commit fixes WinCFI opcodes being incorrectly emitted for test
cases in sign-return-address.ll.
Emit SEH_Nop opcode in emitShadowCallStackEpilogue the same way it is
done in emitShadowCallStackPrologue function - this fixes
12 bytes of instructions in range, but .seh directives corresponding to 8 bytes
error being reported for the epilogue of non_leaf_scs function.
Emit SEH_PrologEnd on the code path in emitPrologue function that may be
taken when pac-ret protection is emitted for a leaf function - this
fixes errors like the following:
starting epilogue (.seh_startepilogue) before prologue has ended (.seh_endprologue) in leaf_sign_all_v83
Stray .seh_endepilogue in leaf_sign_all_v83
