Ava UI: RTL Language Support (#5619)

* Add Hebrew locale files to ItemGroups

* Align all windows RTL for testing

This should be controlled with a binding that selects the appropriate layout based on current language

* Update FlowDirection as Locale changes

* Fix Settings NavigationViewItem FlowDirection

* Fix remaining text

* Fix input menu directionality

* Fix RTL not rendering

* Fix rebase errors
