* Bump version number
* Remove Scheduler indirection
I originally kept the React PriorityLevel and Scheduler PriorityLevel
types separate in case there was a versioning mismatch between the two
modules. However, it looks like we're going to keep the Scheduler module
private in the short to medium term, and longer term the public
interface will match postTask. So, I've removed the extra indirection
(the switch statements that convert between the two types).
We use SyncLane everywhere we used to use InputDiscreteLane or
InputDiscreteHydrationLane. So we can delete them now, along with their
associated lane priority levels.
This commit changes scheduling profiler marks from a format like '--schedule-render-1' to '--schedule-render-1-Sync' (where 1 is the numeric value of the Sync lane). This will enable the profiler itself to show more meaningful labels for updates and render work.
The commit also refactors and adds additional tests for the scheduling profiler package.
It also updates the preprocessor to 'support' instant events. These are no-ops for us, but adding recognition of the event type will prevent profiles imported from e.g. Chrome Canary from throwing with an 'unrecognized event' error. (This will resolve issue #20767.)
* Move preprocessData into a web worker
* Add UI feedback for loading/import error states
* Terminate worker when done handling profile
* Add display density CSS variables
