Instead of having to specify a bitrate and how many packets to use,
the BitrateProber will now use the bitrate to calculate how many
bytes it will use to probe that bitrate instead.
For now, |kMinProbeDurationMs| is set to 15 ms which means that probing
at 1900 kbps will result in 1900/8*0.015 = 3.5 kB used. Since we can
expect packets to be smaller at the beginning of a stream (500 to 700
bytes) this will result in 7 to 5 packets sent for that bitrate, and
should work very similar to how the current initial probing works.
A minimum of 5 packets are always sent.

Now ProbeController can send periodic bandwidth probes when in
application-limited region. This will allow to maintain correct
bottleneck bandwidth estimate, even not all bandwidth is being used.
The feature is not enabled by default, but can be enabled with a flag.
Interval between probes is currently set to 5 seconds.

This reverts commit e30c27205148b34ba421184efe65f6a0780b436d (https://codereview.webrtc.org/1958053002/)
Original reverted cl is in patch set #1.
Changes in following patch sets.
The cl now also make sure SendPacer starts with the configured bitrate provided in a call to CongestionController::SetBweBitrates)()
It turns out that the failing tests in 609816 is due to a bug in the current code that runs the proper at 300kbit regardless of configured start bitrate.
Original cl description:
Remove SendPacer from ViEEncoder
This CL moves the logic where the ViEEncoder pause if the pacer is full to the BitrateController. If the queue is full, the controller reports a bitrate of zero to Call (and BitrateAllocator)

This Relands the cl reviewed in https://codereview.webrtc.org/1917793002/
patchset #1 is a pure reland.
patchset #2 fix an overflow in BitrateProber that caused WebRtcVideoChannel2BaseTest.TwoStreamsSendAndReceive to fail.
