[mediacapture-main] Should getUserMedia be functional in SecureContext only?

youennf has just created a new issue for https://github.com/w3c/mediacapture-main:

== Should getUserMedia be functional in SecureContext only? ==
Following on https://github.com/w3c/webrtc-pc/issues/1945, we might want to update the spec according browser behavior. Currently getUserMedia is rejecting for non secure origins in most (all?) browsers.

A follow-up question might be whether we can further tighten this, for instance:
- Make getSupportedConstraints return an empty dictionary on non secure origins.
- Make enumerateDevices reject on non secure origins.
- Make getUserMedia SecureContext
- Make mediaDevices SecureContext
