Reviewed by Eric Carlson.
We are getting reports of crashes in CapabilityRange constructorrrelease assert
from AVVideoCaptureSource::capabilities().
This means that either the preset list is empty or that some presets have
width/height/frame rate of 0.
We return early in such a case in
RealtimeVideoCaptureSource::updateCapabilities to avoid the crash.
And we return an error from AVVideoCaptureSource::create.
