ARMv8.5 MTE: Add MTE compatible version of strrchr.

Reading outside the range of the string is only allowed within
16 byte aligned granules when MTE is enabled.

This implementation is based on string/aarch64/strrchr.S.

Testing done:
optimized-routines/string/test/strrchr.c
Booted nanodroid with MTE enabled.
Bionic string tests with MTE enabled.
Big endian with Qemu: qemu-aarch64_be
