Revert of Convert MediaRouter mojom apis to intake url::Origin objects instead of strings

Revert of Convert MediaRouter mojom apis to intake url::Origin objects instead of strings (patchset #10 id:180001 of https://codereview.chromium.org/2627463003/ )

Reason for revert:
This broke Media Router:

1) Missing dependency on url/mojo/origin.mojom in extension's context (see https://codereview.chromium.org/2665853002/ for fix)

2) media_router_bindings.js and the extension code were not converted to use Origin objects.
