DO NOT MERGE: Deleted SurfaceControl.remove method

Updated all callers of SC.remove to use Transaction.remove(sc) and apply
immediately since that's the equivalent. Eventually, the transactions
that contain remove could combine with other transactions if it makes
sense to avoid duplicate applies.

Test: SurfaceControlTest
