libc: Prepare support for Armv8.3-A PAuth and Armv8.5-A BTI in *.S
The instruction "bti c" is added through ENTRY*() macro,
using __bionic_asm_custom_entry(f).
The .note.gnu.property section is added with the new macro
NOTE_GNU_PROPERTY(). BTI and PAuth features are automatically
selected based on the presence of __ARM_FEATURE_* macros.
Furthermore, gensyscalls.py got updated to append the new
macro to the generated syscalls-arm64.S.
Test: Tested on FVP with BTI enabled.
