[mediacapture-screen-share] Disable Local Playback During Audio Sharing

chenqiang1986 has just created a new issue for 
https://github.com/w3c/mediacapture-screen-share:

== Disable Local Playback During Audio Sharing ==
We want to add a constraint googDisableLocalEcho in the audio part of 
getUserMedia call.
It only works with audio capturing (either from the whole system or a 
tab).
If set googDisableLocalEcho:true, then we are going to mute the local 
playback of the audio being shared.

For example, if one wants to share a tab, and specifies 
getUserMedia({video:..., audio:{mandatory:{sourceId:, 
googDisableLocalEcho:true}}})
Then during the sharing of the tab, the tab is muted on the sender's 
side. Otherwise the shared tab is still playing out on the sender's 
side.

If one wants to share the full screen with system audio and specifies 
such a parameter. Then we will mute the sender's speaker during the 
sharing.
