GH-128520: Subclass `abc.ABC` in `pathlib._abc` (#128745)

Convert `JoinablePath`, `ReadablePath` and `WritablePath` to real ABCs
derived from `abc.ABC`.

Make `JoinablePath.parser` abstract, rather than defaulting to `posixpath`.

Register `PurePath` and `Path` as virtual subclasses of the ABCs rather
than deriving. This avoids a hit to path object instantiation performance.

No change of behaviour in the public (non-abstract) classes.
