`iswdigit` was implemented (https://github.com/llvm/llvm-project/pull/181635) but not declared in the generated wctype.h (wctype.yaml) and was missing from the Windows config entrypoints. 

This pr declares iswdigit in wctype.h and enables it for the Windows config.

also is part of https://github.com/llvm/llvm-project/issues/185136.
