This one does not have any code that directly manipulates UI actually. This just
intercepts network requests Chrome makes and forward them to intent_helper() as
needed. Can you move this to c/b/c/arc/intent_helper/ as well?

Also, please land this after https://codereview.chromium.org/2436923002/ lands.
https://codereview.chromium.org/2436923002/ has to be merged to M55.
