Add the ability to automatically tether to focus or review (#7489)
* Add support for auto tethering to NVDA
* Use extensionPoints.callWithSupportedKwargs as a fallback for executing event handlers, to support executing events with undefined kwargs.
* Pass an additional parameter for becomeNavigatorObject (isFocus)
* Some small comma fixes and default params are now correct
* Make sure caret moves properly update the braille display when it was tethered to review before
* Some more logging in eventHandler
* More review actions regarding UX
* Update user guide
* DO not update the review position when a tether to focus is expected due to the review move being caused by a focus or caret change
* Fix failing cursor manager test
* Deal with auto tethering in the braille to focus script
* fix braille_toFocus in such a way that it also goes back to focus when reviewing a terminal
* Fix cases where tethering to review and back to focus in browse mode would result in the caret not being followed correctly. This also applies to the braille_toFocus script
* No longer handleGainFocus when tethered to review, and no longer handleReviewMove when tethered to focus
