Evan Shrubsole 6c733eed8e Add exposure criteria to WebRTC stat members.
Recent WebRTC stats spec changes have added restrictions on what stats
are available to JavaScript. This is done to reduce that fingerprinting
surface of WebRTC getStats. For example, stats exposing hardware
capabilities have requirements that must be met by the browser. See [1]
for more details.

This CL adds the types and the enumerations. Stats with these
restrictions should not be added until Chromium has implemented
filtering based on the stat type.
