Remove legacy layer states!
Remove all the unused layer states. Buffer info, frame rate and a few
lingering states remain. But the intention is to completely remove the
legacy layer class and prevent it from being a catch all super class again.
Flag: EXEMPT flag removal
Bug: 330785038
Test: presubmit
