Don't emit RevocableInterfacePtr in mojo's blink bindings

The code that we emit in mojo's blink bindings are sometimes
loaded into non-blink code (see bug) and from there you should not
access code inside blink. Since RevocableInterfacePtr lives inside
blink, that causes dependency and layering violations.

Everyone using blink bindings got something similar to.
ERROR at //out/Default/gen/components/content_settings/core/common/content_settings.mojom-blink-forward.h:20:11: Include not allowed.
#include "third_party/blink/renderer/platform/mojo/revocable_interface_ptr.h"
          ^-----------------------------------------------------------------
It is not in any dependency of
  //components/content_settings/core/common:mojo_bindings_blink
The include file is in the target(s):
  //third_party/blink/renderer/platform:platform
which should somehow be reachable.
___________________

In total there were about 1000 reported dependency errors
because of this.

This fixes this by inlining the few uses and removing the includes.
