Disables caret events for all Terminal objects (PR #10118)
In Mintty, the last character of the prompt was being read when quickly deleting text, just as in Windows Console (see this comment and the "summary of the issue" section in #9986).
This change disables caret events for all Terminal objects by overriding NVDAObjects.behaviors.Terminal._get_caretMovementDetectionUsesEvents, instead of only Windows Console like in #9986.
Closes #1348.
Related to #9933, #9986.
