Rather than passing a BlinkTestRunner unrelated to the current frame
to GCController, we drop its dependency on BlinkTestRunner, as it can
get the task runner from its own WebLocalFrame directly.

Renames BindTo() methods to Install() as they are all there to install
JS bindings, and forward through to other Install() methods.

Moves the GCController binding installation out to the frame, as it is
done per-frame, instead of going through the "global" TestInterfaces.
