Remove the Copresence Endpoints API.

Remove the Copresence Endpoints API.

Since there are no plans to use this API at least for 1H 2015, there is no
point leaving this code in Chrome. Removing this API to reduce code bloat.
We can revisit adding this API again when this work gets prioritized.

This flag is specified since we're deleting an enum from histgrams. This currently breaks the presubmit.
