[libc][wctype] Implement internal UTF8 wctype classification functions (#174607)
Closes [#174604](#174604) This patch implements the internal wide character classification functions with Unicode support. The ASCII paths which were not implemented are taken from [ctype_utils.h](https://github.com/llvm/llvm-project/blob/main/libc/src/__support/ctype_utils.h) The tests mainly cover the dispatch logic between ASCII and UTF8, the UTF8 variants are already comprehensively tested in [wctype_classification_utils_test.cpp](https://github.com/mleleszi/llvm-project/blob/main/libc/test/src/__support/wctype/wctype_classification_utils_test.cpp).
