libc: Add Armv8.3-A PAuth and Armv8.5-A BTI compatibility to *.S
The most notable change is in sigsetjmp/siglongjmp. The former
stores LR signed with the current SP into jmp_buf. Calling siglongjmp
reads a signed LR and the corresponding SP from jmp_buf. This way not
only the checksum provides some means of integrity protection but
Pointer Authentication too.
Test: Tested on FVP with BTI enabled.
