Revert "Remove redundant calls to onCameraAccessPrioritiesChanged."

This reverts commit 03befa0c.

Reason for revert: The assertion made that a uid state change implies a proc oom adj change is not true on GSI. There may be a more complex way of handling this, but it's low priority to implement it.
