[TIR][Schedule] Method returning the function being worked on (#14593)
PR #11999 introduces the sugar method `work_on` to TIR Schedule, with
a field `func_working_on_` newly added to the ScheduleNode. In some
cases we may want to know which function a ScheduleNode is working on,
which is not supported previously.
Therefore, this PR introduces a method to ScheduleNode that returns
the function (more accurately, GlobalVar) currently being worked on.
With this we are able to know the function being worked on.
