Reland "[Battery]: Delay start of TaskQueuePacedSender." Take 3

This is a reland of 89cb65ed663a9000b9f7c90a78039bd85731e9ae
... and f28aade91dcc2cb8f590dc1379ac7ab5c1981909
... and 2072b87261a6505a88561bdeab3e7405d7038eaa

Reason for revert: Failing DuoGroupsMediaQualityTest due to missing
TaskQueuePacedSender::EnsureStarted() in google3.
Fix: This CL adds the logic behind TaskQueuePacedSender::EnsureStarted,
but initializes with |is_started| = true. Once the caller in google3 is
updated, |is_started| can be switched to false by default.

> Original change's description:
> Reason for revert: crashes due to uninitialized pacing_bitrate_
> crbug.com/1190547
> Apparently pacer() is sometimes being used before EnsureStarted()
> Fix: Instead of delaying first call to SetPacingRates(),
> this CL no-ops MaybeProcessPackets() until EnsureStarted()
> is called for the first time.
