Latch Unsignaled when only a single layer is being updated.

Three conditions are introduced.
DISABLED (Default for now): This is when latch unsignaled is completely disabled.
AUTO: This is when we will latch for the single layer update. Further refinements will be done in b/200284381
ALWAYS: This will latch unsignaled no matter what the change is.

BUG: 198189193
