Joe Tsai	a8fbe284b2	taildrop: fix theoretical race condition (#9866) ... WaitGroup.Wait should not be concurrently called WaitGroup.Add. In other words, we should not start new goroutines after shutodwn is called. Thus, add a conditional to check that shutdown has not been called before starting off a new waitAndDelete goroutine.

Joe Tsai	c2a551469c	taildrop: implement asynchronous file deletion (#9844) ... File resumption requires keeping partial files around for some time, but we must still eventually delete them if never resumed. Thus, we implement asynchronous file deletion, which could spawn a background goroutine to delete the files. We also use the same mechanism for deleting files on Windows, where a file can't be deleted if there is still an open file handle. We can enqueue those with the asynchronous file deleter as well.
