        src/sys/arch/aarch64/include: armreg.h asm.h

Log Message:
"options ARMV83_PAC" is now supported for gcc as well.

- add "-msign-return-address=all" to CFLAGS for gcc when specified options ARMV83_PAC
- AARCH64REG_{READ,WRITE}_INLINE3 macro can now use the APIAKey registers in both gcc and llvm.
  llvm requires asm(".arch armv8.3-a"), whereas gcc requires __attribute__((target("arch=armv8.3-a"))).
- use ".arch armv8.3-a" rather than ".arch armv8.3-a+pac" in *.S for llvm.
