LOG: [libc][docs] List `rand` and `srand` as supported on the GPU (#96757)

Summary:
I initially didn't report these as supported because they didn't provide
expected behavior and were very wasteful. The recent patch moved them to
a lock-free atomic implementation so they can now actually be used.

Removed:
