[ProtonAOSP] Switch to arm-optimized-routines for arm64lineage-18.1
This replaces the following string functions with implementations from
arm-optimized-routines [1]:
- memchr
- strchr
- strcmp
- strlen
- strncmp
- strnlen
- memcmp
- memcpy (NEON variant)
- memmove
- memrchr
- memset
- stpcpy
- strchrnul
- strcpy
- strrchr
- wmemmove
All string functions supported by arm-optimized-routines were added as
of upstream commit e823e3abf5f89ecba58a10fc0fd82c13d9984b6b. The NEON
variant of memcpy was used with the assumption that all of our arm64
targets support NEON.
