Change MediaStreamVideoSource::StartSourceImpl to use VideoCaptureFormat instead of VideoCaptureParams.
MediaStreamVideoSource only need the VideoCaptureFormat and thus should not pass VideoCaptureParams to its implementations.
This just a small code cleanup and does not change any behaviour.

No LGTM from a valid reviewer yet. Only full committers are accepted.
Even if an LGTM may have been provided, it was from a non-committer or
a provisional committer, _not_ a full super star committer.

Note that this has nothing to do with OWNERS files.

LGTM

you might still need content/renderer/pepper approval though.
