When pathlib.WindowsPath.glob() evaluates a literal (non-wildcard) pattern segment, it returns paths using the case of the pattern segment, rather than the real filesystem case. This problem does not affect segments involving * or ** wildcards.

>>> from pathlib import WindowsPath
>>> next(WindowsPath().glob('LIB/PATHLIB.*'))
WindowsPath('LIB/pathlib.py')  # 'LIB' should be 'Lib'

We now use `_WildcardSelector` to evaluate literal pattern segments, which
allows us to retrieve the real filesystem case.

This change is necessary in order to implement a *case_sensitive* argument
(see pythonGH-81079) and a *follow_symlinks* argument (see pythonGH-77609).

Fixed in 3.12. Not backported as it relies on other changes in the 3.12 line.
