Clean up timeoutMs-related implementation details (#19704)
Browse files Browse the repository at this point in the history 
* Disable busyDelayMs and busyMinDurationMs

Refer to explanation in previous commit.

* Remove unnecessary work loop variables

Since we no longer support SuspenseConfig options, we don't need to
track these values.

* Remove unnecessary Update fields
