This change prepares for later CLs that partly replaces
logic in the module that depends on the Module system
for logic that depends on task queues.
The change also changes SendTransport::SendRTCP
to schedule packet reception with the simulated time
controller. This fixes the problem that SendRTCP itself
updates the simulated time which makes it hard to
understand the tests.
Finally, GlobalSimulatedTimeController was updated
to support addition of custom SimulatedSequenceRunners
like SendTransport.
