enhance: Simplify querynode tsafe & reduce goroutine number (#38416)
Related to #37630

TSafe manager is too complex for current implementation and each
delegator need one goroutine waiting for tsafe update event.

Tsafe updating could be executed in pipeline. This PR remove tsafe
manager and simplify the entire logic of tsafe updating.
