AArch64: Add libcall impl declarations for __arm_sc* memory functions (#144977)
These were bypassing the ordinary libcall emission mechanism. Make sure
we have entries in RuntimeLibcalls, which should include all possible
calls the compiler could emit.
Fixes not emitting the # prefix in the arm64ec case.
