GH-128520: Merge pathlib._abc into pathlib.types (#130747)

Browse source 
There used to be a meaningful distinction between these modules: `pathlib`
imported `pathlib._abc` but not `pathlib.types`. This is no longer the
case (neither module is imported), so we move the ABCs as follows:

- `pathlib._abc.JoinablePath` --> `pathlib.types._JoinablePath`
- `pathlib._abc.ReadablePath` --> `pathlib.types._ReadablePath`
- `pathlib._abc.WritablePath` --> `pathlib.types._WritablePath`

"""
Abstract base classes for rich path objects.
This module is published as a PyPI package called "pathlib-abc".
This module is also a *PRIVATE* part of the Python standard library, where
it's developed alongside pathlib. If it finds success and maturity as a PyPI
package, it could become a public part of the standard library.
Three base classes are defined here -- JoinablePath, ReadablePath and
WritablePath.
