[AArch64][compiler-rt] Add Pointer Authentication support for VFORK.
The LR is stored to off-stack spill area where it is vulnerable.
"paciasp" add an auth code to the LR while the "autiasp" verifies that so
LR can't be modiifed on the spill area.
Test: build with -DCMAKE_C_FLAGS="-mbranch-protection=standard",
run on Armv8.3 capable hardware with PAuth.
