Philipp Hancke 33c7edd58a Enable DD and VLA header extensions by default for Simulcast/SVC
When Simulcast (more than one encoding) or SVC (a scalability mode
other than the default L1T1) is used, enable the AV1 Dependency
Descriptor and the video-layer-allocations RTP header extensions by
default.

The RTP header extensions API can be used to disable them if needed.
