Yannick Welsch 1ba6783780 Schedule commands in current thread context (#54187)
Changes ThreadPool's schedule method to run the schedule task in the context of the thread
that scheduled the task.

This is the more sensible default for this method, and eliminates a range of bugs where the
current thread context is mistakenly dropped.

Closes #17143
