svtav1enc: Drain and completely reallocate the encoder instance on caps changes

Browse source 
The encoder does not support reconfiguration, and only deinitializing it
and then initializing it again causes deadlocks.

Also only reconfigure and drain the encoder if the video info has
actually changed.
