GH-130614: pathlib ABCs: revise test suite for Windows path joining (#131016)
Test Windows-flavoured `pathlib.types._JoinablePath` in a dedicated test module. These tests cover `LexicalWindowsPath`, `PureWindowsPath` and `WindowsPath`, where `LexicalWindowsPath` is a simple implementation of `_JoinablePath` for use in tests.
