editor: Hide mouse cursor also for movements and selections (#27677)

This enables hiding mouse cursor even on cursor movements like up, down,
etc. or selections made using keyboard, etc.

Renamed existing boolean setting "hide_mouse_while_typing" to
"hide_mouse". It can have three values: `on_typing_and_movement`,
`on_typing`, `never`.

Release Notes:

- Now mouse cursor hides even when you navigate, or make selections
using keyboard in editor. This behavior can be changed by setting
`hide_mouse` to `on_typing_and_movement`, `on_typing` or `never`.
