3e06cfcaee gh-135953: Reduce memory usage of stack collectors (#138875) 
The stack collector base class keeps all frames until export() is
called, which causes significant unnecessary memory usage. Instead, we
can process the frames on the fly in the collect call by dispatching the
aggregation logic to the subclass through the process_frames method.

805e3368d6 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__()`.
