pythonGH-128520: Divide pathlib ABCs into three classes
c3bb4ff 
In the private pathlib ABCs, rename `PurePathBase` to `JoinablePath`, and
split `PathBase` into `ReadablePath` and `WritablePath`. This improves the
API fit for read-only virtual filesystems.

The split of `PathBase` entails a similar split of `CopyWorker` (implements
copying) and the test cases in `test_pathlib_abc`. For a couple of reasons,
this isn't quite possible yet.

In a later patch, we'll make `WritablePath` inherit directly from
`JoinablePath` rather than `ReadablePath`.

pythonGH-128520: Subclass abc.ABC in pathlib._abc
95688bb 
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.
