SF: Optimize layer history in scheduler
Register layers with LayerHistory by storing a weak pointer rather than
allocating a LayerHandle. Query layer visibility when needed instead of
synchronizing it to LayerInfo whenever Layer::isVisible is called. Store
active/inactive layers in contiguous memory instead of two hash maps for
cache efficiency, and minimal allocation and run time of operations like
clearing history. Remove redundant ref-counting, locking, and frequency-
period conversion in LayerInfo. Avoid sleeping in unit tests.
This is also prework for per-display layer history.
