[camera_android_camerax] Re-land "Force new Surface for each SurfaceRequest"

[camsim99]

Important

(DONE ✅ in flutter/flutter#172384) flutter/flutter#169899 must be rolled into packages AND be in Flutter stable for this to land. I will try to cherry-pick this change into 3.32 stable once the 3.35 beta is cut.

Note

This includes a bunch of unrelated reformatting of files. Going to try to land this first in #9701.

Re-lands #9360.

Since timing for Surface requests cannot be guaranteed, request a new Surface from SurfaceProducer.getSurface each time a Surface is requested for rendering the camera preview to.

Fixes flutter/flutter#155294.
Fixes flutter/flutter#169506.
