de5a74a35b Replace switches in scalability mode utility functions 
Instead, use an array indexed on the scalability mode. This is a
follow-up on https://webrtc-review.googlesource.com/c/src/+/344760.

fe24f58c73 Report proper VP9 scalability mode with layer activation. 
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.

33155d763c svc: Remove references to bogus modes 
Those never existed, were likely a copy-paste error in the spec
that we somehow inherited.

a1a7c638ec Let PCF.GetRtpSenderCapabilities return codecs' scalabilityModes. 
Also move ScalabilityModeToString to api and add RTC_EXPORT so that
Chromium can use it.
