Adds a reporting API to help developers deploy cross-origin opener policy.

Motivation

We want to provide a reporting API for cross-origin opener policy (COOP) to help developers deploy it on their websites. In addition to reporting breakages when COOP is enforced, we want to provide a report-only mode for COOP. The report-only mode for COOP will not enforce COOP, but it will report potential breakages that would have happened had we enforced COOP.
