This changes the libvpx VP9 encoder to generate the scalability mode based on the current encoding parameters when using layer activation.
Tested: Ran with L3T3_KEY reduced to L2T3_KEY and L1T3 due to bandwidth or layer activation. Added unit tests.

Instead, always use VideoSendStream::Start.
VideoSendStream::StartPerRtpStream was used for controlling if
individual rtp stream for a RtpEncodingParameter should be able to send RTP packets. It was not used for controlling the actual encoder layers.
With this change RtpEncodingParameter.active still controls actual encoder layers but it does not control if RTP packets can be sent or not.
The cleanup is done to simplify code and in the future allow sending
probe packet on a RtpTransceiver that allows sending, regardless of the
RtpEncodingParameter.active flag.

Because of our asymmetrical codec situation, it's possible to have
send only codecs that we cannot negotiate even with ourselves.
This means that we should not have a DCHECK, but just a plain error.

There are now multiple ways to configure VP9 L1Tx:
- Legacy API: configure legacy SVC and disable encodings, this gets
interpreted as disabling spatial layers (non-standard API hack).
- Standard API: configure scalability_mode. This can be done either
with a single encoding or multiple encodings. As long as only one
encoding is active we get a single L1Tx ssrc, same as legacy API.
Due to a bug, the ApplySpatialLayerBitrateLimits() logic which tweaks
bitrates was only applied in the legacy API code path, not the standard
API code path, despite both code paths configuring L1Tx.
The issue is that IsSimulcastOrMultipleSpatialLayers() was checking if
`number_of_streams == 1`. This is true in legacy code path but not
standard code path. The fix is to look at
`numberOfSimulcastStreams == 1` instead, which is set to the correct
value regardless of code path used.
This CL adds comments documenting the difference between
`number_of_streams` and `numberOfSimulcastStreams` to reduce the risk
of more mistakes like this in the future.

This CL introduces PeerConnectionEncodingsIntegrationParameterizedTest,
which is based on PeerConnectionEncodingsIntegrationTest but covers all
codecs using INSTANTIATE_TEST_SUITE_P (VP8, VP9, H264, AV1).
This applies to all standard paths, which in the case of VP9 and AV1
requires opting in to it by specifying scalabilityMode and
scaleResolutionDownBy. They are also limited to L1Tx because the other
codecs don't support SVC.
The VP9-only tests continue to run as TEST_F with
PeerConnectionEncodingsIntegrationTest.

This is a pure rename+move of PeerConnectionSimulcastMediaFlowTests.
The reason for renaming is to reflect that a) this is an integration
test, not a unit test, and b) not all of the tests use simulcast (some
use a single encoding, i.e. singlecast or SVC).
Shared helper functions between PeerConnectionEncodingsIntegrationTest
and PeerConnectionSimulcastTests are placed in a test-only util file.
