aarch64: Add pac-ret support to assembly files
Use return address signing in assembly files for functions that save
LR when pac-ret is enabled in the compiler.

The GNU property note for PAC-RET is not meaningful to the dynamic
linker so it is not strictly required, but it may be used to track
the security property of binaries. (The PAC-RET property is only set
if BTI is set too because BTI implies working GNU property support.)
