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.

When allocating bitrate, some parts of the coded directly uses the bitrate parameter, while others lets it be capped by VideoCodec.maxBitrate. This may result in an inconsistency between expected and actual number of temporal layers, causing a crash.
Even better would be to update VideoCodecInitializer to not create
VideoCodec instances where there's not enough maxBitrate to activate
all spatial layers - but that's a much more complex issue.

Fallback to a default value if the scalability mode is unset or not supported by the codec.
The fallback logic is only enabled if the scalability mode is configured for any of the encodings for now (i.e. initial default values are not set).

The VP9 encoder may drop a frame internally which will not advance the
frame pattern. Consider the following scenario where only spatial layer
0 and temporal layer 0 is active:
1. Key frame encoded
2. Spatial layer 1 is activated
3. Delta T0 dropped
4. Delta T0 encoded
No S1T0 frame is encoded in (1) since it's not active. When
NextFrameConfig is called in (3) it will say that future frames may
reference T0 on both S0 and S1, but it's then dropped.
On step (4), the SVC controller essentially thinks it's encoding a new
picture and will happily reference the T0 on what it thinks is the first
delta frame. However, this is actually still the key frame and since
there was no S1T0 frame produced it will reference an invalid buffer.
To fix this, only say it's possible to reference a T0 frame after it has
been successfully encoded.

When spatial scalability is used, both vpx and aom set key frame flag
for all spatial layers of the first frame, while rtp code expect it to
be set only on the frame without spatial dependencies.
That creates confusion for the frame dependency calculator.
Simplest solution seems to ignore that confusing signal and instead
rely encoder wrappers update frame buffer usages when key frame is generated.
