[pynput] Fix annotations for event callbacks (#15857)

They are designed to accept any number of arguments up to the maximum amount, so `on_click()` and `on_click(x, y)` are both perfectly valid callbacks.

Also fix callback return types. Technically they accept any return type, but as the only effect is returning `False` stops the iteration, then it makes sense to limit it to `bool | None`.
