Hide the mouse when the user is typing in the editor - take 2 (#27519)

Closes #4461

Take 2 on https://github.com/zed-industries/zed/pull/25040. 

Fixes panic caused due to using `setHiddenUntilMouseMoves` return type
to `set` cursor on macOS.

Release Notes:

- Now cursor hides when the user is typing in editor. It will stay
hidden until it is moved again. This behavior is `true` by default, and
can be configured with `hide_mouse_while_typing` in settings.
