Fix mojom::ResourceUsageReporter exposure via content child capabilities

Adds the interface to the browser capability for content_gpu in
Chrome's overlay.

Moves the interface from content_renderer_manifest.json to Chrome's
content_renderer overlay where it belongs.

Adds a Chrome overlay for content_plugin and adds the interface
there as well.
