`PurePath.__init__()` incorrectly uses the `_raw_paths` of a given
`PurePath` object with a different flavour, even though the procedure to
join path segments can differ between flavours.
This change makes the `_raw_paths`-enabled deferred joining apply _only_
when the path flavours match.

GH-119169: Implement `pathlib.Path.walk()` using `os.walk()` (GH-119573)
For silly reasons, pathlib's generic implementation of `walk()` currently
resides in `glob._Globber`. This commit moves it into
`pathlib._abc.PathBase.walk()` where it really belongs, and makes
`pathlib.Path.walk()` call `os.walk()`.
