Reland "[Media Router] Converts integration tests to run on Chromium waterfall."

This is a reland of aa57fe6dc96b40a58acc1ed6c268f47a881b590e

Original change's description:
> [Media Router] Converts integration tests to run on Chromium waterfall.
>
> This updates the Media Router integration tests so they run in the
> Chromium waterfall with the open source Media Router component
> extension and its mock (test) Media Route Provider.
>
> Additional changes:
>
> - Removes extension from top level BUILD.gn as it is only used for
>   browser tests at the moment.
> - Splits the targets for Media Router browser tests into integration tests
>   (part of main browser_tests suite), e2e tests (which require the
>   external component extension), perf tests, and shared support code.
> - Renames the "test" extension to the "telemetry" extension used for perf
>   tests to avoid confusion.
> - Updates README files
> - One test is not compatible with the Chromium component and need
>   to be fixed.  Bugs  818767  filed for follow-up.
