GH-128520: pathlib ABCs: improve protocol for 'openable' objects (#134101) 
Rename `pathlib._os.magic_open()` to `vfsopen()`. The new name is a bit
less abstract, and it aligns with the `vfspath()` method added in 5dbd27d.

Per discussion on discourse[^1], adjust `vfsopen()` so that the following
methods may be called:

- `__open_reader__()`
- `__open_writer__(mode)`
- `__open_updater__(mode)`

These three methods return readable, writable, and full duplex file objects
respectively. In the 'writer' method, *mode* is either 'a', 'w' or 'x'. In
the 'updater' method, *mode* is either 'r' or 'w'.

In the pathlib ABCs, replace `ReadablePath.__open_rb__()` with
`__open_reader__()`, and replace `WritablePath.__open_wb__()` with
`__open_writer__()`.
