Refactors and expands referrer policy browsertests

This patchset contains two changes to the referrer policy browsertests: 1. Refactor the "reduced referrer granularity flag" tests to use a parameterized test---this will allow easy expansion to test additional capping logic, e.g. the "no referrers at all" flag, which is currently missing test coverage. (This will be remedied by a follow-on CL.) 2. Add tests for subresource requests (by registering a test server callback to inspect the `Referer` headers sent along with the requests).
