JoeDow 8a1cc69717 Layout: minor optimizations and bugfix for non-functional details (#38197) ... This change adds some minor optimizations and bugfix for non-functional details with seperated commits: - fix the omission that stop use `Rayon` in single-thread mode - add trace for incremental box tree construction - fix the bug that failed to skip reflow entirely when there is no need for `restyle` and a fragment tree has already been built. - add trace for stylist preparation during reflow. In certain scenarios, this phase might take up a significant amount of time, such as when there are a large number of shadow trees. Testing: This should not change observable behavior and is thus covered by existing WPT tests. --------- Signed-off-by: sharpshooter_pt <ibluegalaxy_taoj@163.com>		2025-07-22 10:56:52 +00:00
