Nicholas Van Sickle 867ae23664 Make Viewport input events fully Qt based (#2142)
* Make Viewport input events fully Qt based.

This should fix an issue with Qt touch event -> mouse event translation in the Editor, and may also fix issues with the Mac Editor and remote desktop (though, lacking the requisite hardware, I can test precisely none of these things personally).

See https://github.com/o3de/o3de/issues/1889

- Adapted LegacyViewportCameraController to use Movement::X & Y (mostly for testing purposes, it's on the slate for being removed soon)
- Moved cursor capture logic from RenderViewportWidget into QtEventToAzInputManager so that it can make sure it generates correct movement deltas
- Removed ViewportMouseCursorRequests::PreviousViewportCursorScreenPosition to have our viewport controllers use our dedicated Movement::X and Y channels instead, which will work in the launcher
