liyuqian 3f5e53a4c7 Compute cull_rect and optimize in Layer::Preroll (flutter/engine#6923) 
This PR replaces the unused `PrerollContext::child_paint_bounds` with `PrerollContext::cull_rect` so we can prune unnecessary preroll tasks (especially cache) based on clips. This PR fixes https://github.com/flutter/flutter/issues/24712

Performance test has been added (https://github.com/flutter/flutter/pull/25381) to make sure that we won't regress again in the future.

Note that the cull_rect here is very similar to those removed in https://github.com/flutter/engine/pull/6352 .     We can't compute cull rects in SceneBuilder because of retained layers. But we can still compute and use them to optimize performance in Preroll.

Flow

Flow is a simple compositor based on Skia that the Flutter engine uses to cache recoded paint commands and pixels generated from those recordings. Flow runs on the GPU thread and uploads information to the GPU.
