Add support for MediaStreamTrack.(getCapabilities|getSettings) method

[rejebsab]

MediaStreamTrack.getCapabilities method hasn't been implemented but it's in the spec.

MediaStreamTrack.getSettings is in the spec and not implemented also.
https://www.w3.org/TR/mediacapture-streams/#dom-mediastreamtrack-getsettings

We never said this was the full spec to the contrary.

Still can be a nice improvement for the future.

Any approximative due date for the 7.0.x release version please?

[hthetiot]

I might be able to put that in 6.0.x, I will see what I can do.

@hthetiot maybe it's dumb question, but I'm newbie in using iosrtc plugin so can't understand possible obvious thing - are getCapabilities|getSettings was implemented in iosrtc only as empty stubs just to avoid exceptions on runtime or I should search real implementation somewhere else?

Comment on closed issue is a sine @RSATom please create separate issue. But to answer this methods are SHAM (fake) for now.
