If e.g. CPU adaptation reduces input video size too much, video pipeline would
reduce the number of used simulcast streams/spatial layers. This may result in
disabled video if some streams are disabled by Rtp encoding parameters API.

* Increase 540p bitrate to 1.2mbps from 0.9mpbs.
960x540 bitrate was by far smallest in terms of bits per pixel. This change
brings it closer to other resolutions.
* Interpolate max/target/min bitrates for non-standard resolutions based
on number of pixels.

When using simulcast, if the source is too small, it might end up generating
layer sizes that are problematic for hardware encoders.
We can temporarily restore the old behavior that adapts the layer count to the source size until we fix the HW encoder behavior.

Some applications are having issues controlling how many active simulcast
layers they have and configuring them when the source track changes size
and rely on the old behavior automatically reducing the layer count.
Using the WebRTC-LegacySimulcastLayerLimit field trial, they can get back
the old behavior until they transition to the newer API.

As per the spec, you should be able to use simulcast with screenshare.
We remove the field trial for it and keep the old behavior only for
screenshare sources with conference flag on.

The exponent is allowed to be set through the field trial.

When simulcast screenshare is enabled, the max bitrate for the high
quality stream can be limited based on the resolution.
This CL fixes a bug where that limit could get so low that it is below
the min bitrate of the top layer, which in turn could cause the encoder
to fail initialization.
