Ensure opacity is update on the VRI SC when format changes

Browse Source 
Opacity is set based on format change. Previously, WMS would recreate
the surface when the format was changed and set the new opacity.
However, since ag/13348893, format changes no longer recreate a surface.
Therefore, we also need to update the opacity flag when format is
changed in VRI.

Test: Play video from camera app
