Broken Number Pad on macOS in New Interactive Interpreter in 3.13.0

Bug report

Bug description:

When using the new interactive interpreter, digits can no longer be entered using the number pad on a standard full-size Mac keyboard. This did not occur in 3.12 or earlier and is likely not desired behaviour.

Workaround:
Pressing the "clear" button on the keyboard will fix this (acting like a toggle). I suspect this is because the Mac clear key shares a key code with "Num Lock" on Windows, where this is standard behaviour.

This is NOT standard behaviour on macOS, however. MacOS keyboards do not have a "Num Lock", nor do their keyboards have markings for secondary actions as with windows keyboards.

I imagine that very few users would recognize that their number pad is not working in the new Python interpreter because of a mis-applied platform-specific key binding of the "clear" key.

CPython versions tested on:

3.13.0

Operating systems tested on:

macOS

Start by reproducing the number-pad behavior in the new interactive interpreter on macOS with Python 3.13.0, comparing it with Python 3.12 or earlier. Trace the interpreter's macOS key handling, especially the clear-key behavior; done means number-pad digits work normally without pressing clear and existing behavior remains intact.
