[RFC PATCH 1/9] ntdll/tests: Add tests for iswctype.

[Jeff Smith]

Signed-off-by: Jeff Smith

This series essentially supersedes the series starting with
https://source.winehq.org/patches/data/176232

It no longer contains anything regarding IsCharBlankW, as that is
associated with a different instance of the wctype table, and this
series is long enough as-is.

The first three patches are focused on ntdll, while the remainder
are focused on msvcrt, ucrtbase, etc.
