In M113 we made it possible to opt-in to spec-compliant VP9 using
scalabilityMode and scaleResolutionDownBy. Since this would change
behavior in some edge cases a kill-switch flag was also added.
It turns out it was not needed (current Stable: M114) so we can remove
the flag.

Prior to this CL, the video `jitterBufferDelay` stat was the accumulated current delay, which is a smoothened version of the target delay. This is not correct according to the spec [1]. Rather, the stat should be the accumulated time spent in the jitter buffer, for all emitted frames. This CL fixes this spec compliance problem.
Expect changes to test metrics and product monitoring as this CL rolls out.

When the feature is on, packets are collected in RtpSenderEgress. On

This makes "WebRTC-AllowDisablingLegacyScalability" enabled-by-default,
meaning any app can opt-in to spec-compliant simulcast when
scalabilityMode is specified.
The opt-in criteria is also made more restricitve: you now have to
specify both scalabilityMode and scaleResolutionDownBy to get simulcast,
otherwise you continue to get legacy "single stream" path.
The reason for this is not to cause any surprises in use cases like
[{scalabilityMode:"L1T1", active:true}, {active:false}, {active:false}]
In cases like this where scaleResolutionDownBy is not specified, it
defaults to 4:2:1 if simulcast is used but the legacy path caps it to
one stream, meaning full resolution. By restricing simulcast only to
cases that set scaleResolutionDownBy, we remove the risk of an app
getting a different resolution than expected due to opt-in.

Attempting to ship "WebRTC-AllowDisablingLegacyScalability" revealed a
DCHECK that happens when negotiating 3 VP9 streams prior to the
setParameters() call:
1. By default, `scalability_mode` is missing, so those 3 streams
defaulted to legacy SVC, meaning only a single stream is used.
2. Then, setParameters() was called to make
`encodings[0].scalability_mode = "L2T2_KEY"` and
`encodings[1-2].active = false`. The inactive streams were just
dummies and never expected to exist.
Without simulcast support this is OK, because both 1) and 2) are
interpreted to have a single stream. But with simulcast support, 1) is
interpreted as single stream and 2) as three streams (1 active, 2
inactive). This should be roughly the same setup, but our code treats
them differently.
The DCHECK crash was a mismatch in number of streams in one of the
layers.
The fix is to re-create the streams when the number of streams change
for this reason. The new test revealed other issues and fixes too:
- Support for multiple spatial layers (e.g. "L2T2_KEY") when multiple
encodings exist but only one encoding is active.
- Allow inactive layers not to have a scalability mode set.
A laundry list (https://crbug.com/webrtc/15028) has been created to
update known places doing "if streams == 1" that need to do "if
active streams == 1" instead.

The goal of the VP9 simulcast project is that when `scalability_mode`
is set, multiple encodings are always interpreted as simulcast, even
if VP9 or AV1 is used. This CL makes this so, but only if the flag
"WebRTC-AllowDisablingLegacyScalability" is "/Enabled/". This allows us
to make "SendingThreeEncodings_VP9_Simulcast" EXPECT VP9 simulcast.
When we are ready to ship we will remove the need to use the field
trial, but before we ship this we'll want to revisit if
SvcRateAllocator can be updated to support simulcast. (Today if we use
SvcRateAllocator when VP9 simulcast is used, all encodings except the
first one get bitrate=0, causing the test to fail because media is not
flowing on all layers.) For now, a TODO is added.

Encoders that do not support simulcast in the first place does not
expect to have to handle simulcast configurations, and as such may not
necessarily return
WEBRTC_VIDEO_CODEC_ERR_SIMULCAST_PARAMETERS_NOT_SUPPORTED from
InitEncode().
This CL updates EncoderSimulcastProxy to respect this info to avoid
silent errors when LibvpxVp9Encoder (which does not support simulcast)
is attempted to be used in simulcast.
Alternatively we can try to get rid of EncoderSimulcastProxy altogether
since SimulcastEncoderAdapter already has a passthrough mode. A TODO is
added to get rid of the proxy.

This reverts commit 18c869bc36b342cd4a79947067e52a93a04a7808.
Reason for revert: Added a field trial that allows landing the code without affecting performance in prod.
This CL also incorporates subsequent CLs that also had to be reverted.
