Bump Camera Example Plugin Apps Targetsdk Versions

[jesswrd]

Bumped targetsdk versions of example app plugins for camera, camera_android, and camera_android_camerax. Deleted Capture specific image resolutions integration. The Android CameraX team confirmed the result coming from the CameraX side is correct and works as they expect. This means the supported output sizes cannot fulfill our test case assumptions.

For 'camera_android_camerax', we use the automatic selection described here, and it willl automatically choose, so we can't control the outcome. Even if we specify, the resolution is not gauranteed.

camera would have the same behavior as camera_android_camerax because camera's android implementation defaults to camera_android_camerax behavior.

For camera_android we cannot choose the aspect ratio here. If there's an unsupported size, it "falls through" to the next smallest size, which means we cannot choose the final resolution. Example high quality aspect ratio here, and logic for final resolution here.

Fixes flutter/flutter#154682
