Use RenderFrameHost::AddMessageToConsole for app banner debug logging.

Use RenderFrameHost::AddMessageToConsole for app banner debug logging.

This CL replaces the custom IPC message used by the app banner debug log
to add a message to the devtools console with the existing
AddMessageToConsole method in RenderFrameHost. This allows boilerplate
IPC scaffolding to be removed.
