LOG: [libc] enable most of the entrypoints on aarch64 (#101797)
This is a non-feature change that enables most of the entrypoints for
aarch64 based runtime builds. It fixes an additional problem that some
compiler-rt targets are not defined at the time of dependency checking
thus leading to false-negatives.
