Implement RTC[In/Out]boundRtpStreamStats.contentType.
Spec: https://henbos.github.io/webrtc-provisional-stats/#dom-rtcinboundrtpstreamstats-contenttype
This already exists as a goog-stat. This CL only plumbs the value to the
new stats collector.
Note: There is currently no distinction between the extension being
missing and it being present but the value being "unspecified". Until
https://crbug.com/webrtc/10529 is fixed, this metric is only exposed if
SCREENSHARE was present.
