[Media Router] Custom Controls 1 - Add MediaStatus, MediaRouteController, and
mojo interfaces

This CL adds MediaRouteController that will forward media controller commands
from the custom controls WebUI to the Media Router component extension, and
will receive MediaStatus updates from the extension which it then will forward
to its Observer(s) (= to the WebUI).

This patch includes mojo interfaces/structs that were first reviewed in this
patch [1]. The MediaController mojo interface will be implemented in the
component extension (not a part of Chromium), and will receive commands from
MediaRouteController. MediaRouteController implements the MediaStatusObserver
mojo interface and receives updates from the extension. Typemapping between
media_router::mojom::MediaStatus and media_router::MediaStatus is also
included in this CL.

Changes in extensions/renderer/ are for exposing the new mojo interfaces to
the component extension.

The Chromium-side implementation of custom controls redesign will be done in
these patches:
1. Mojo/MediaStatus/MediaRouteController:     this patch
2. MediaRouter::GetRouteController():         http://crrev/2728543009
3. MRUI/MRWebUIMessageHandler:                http://crrev/2731033002
4. Custom controls WebUI:                     http://crrev/2725503002
