- set the preview scale type to fitStart
- both the preview and image capture would use the same size
- some other code cleanups to remove unused code / formatting changes
- CameraX video allowed predefined buckets of qualities UHD, FHD, HD, SD (defined in VideoQuality enum),
the CameraXPreview is configured to use the highest quality and
CameraX will select the closest corresponding resolution supported by the device.
- tentatively add ChangeResolutionDialogX (which would be renamed back to ChangeResolutionDialog) to give user option to select photo resolution and video qualities
- add ImageQualityManager which performs the same operation for getting all resolutions supported by a device using the Camera2 API, as defined in the legacy CameraPreview
- add VideoQualityManager to manage saving/ getting user selected quality.
