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.

e6b4cbe606 Add SVC fallback.
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).

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

79d566b0cf New enum ScalabilityMode.
Used instead of string representation in lower-levels of encoder configuration, to avoid string comparisons (with risk of misspelling) in lots of places.
