Summary

We want to unify DefaultLane, SyncLane, and ContinuousLane into just SyncLane, and use a separate field on the root to track whether they should be scheduled with queueMicrotask, requestAnimationFrame, or completely synchronously (in the case of flushSync).
This PR is for unifying DefaultLane and SyncLane.

The main change is that EventPriorities no longer strictly maps to Lane. Instead, it also contains extra bits for UpdateType, so that we can distinguish DefaultUpdate from DiscreteUpdate since now they both are on the sync lane.

TODO:

  • Still a lot of test failure need to figure out

How did you test this change?
