[libc] Migrate wctype_utils to use wchar_t where applicable. (#166234)

This is a counterpart of
https://github.com/llvm/llvm-project/pull/166225 but for wctype_utils
(which are not yet widely used). For now, I'm just changing the types
from wint_t to wchar_t to match the regular ctype_utils change. The next
change may rename most of the functions to match the name of ctype_utils
variants, so that we could be calling them from the templated code
operating on "const char*" and "const wchar_t*" strings, and the right
function signature would be picked up.
