SF: Frontend fixes for issues surfaced by SurfaceFlinger_test

- separate color and bgcolor in layer state so we don't set a color
 on a layer without a buffer
 - avoid using legacy layer state when latching a buffer
 - fix callback issue where invisible or offscreen layers were not invoking
 the callbacks
 - pass in layer snapshot for trusted presentation state
 - fix a screenshot issue where the root layer was skipped
 - pass in framerate changes to layer history

Test: presubmit
Test: atest SurfaceFlinger_test with new fe
Bug: 238781169
