Slow Reports - Add message filter to trigger background traces from child processes.
At the moment, we want to trigger background traces from UMA callbacks, but you can only set a callback in the same process. This CL adds a message filter for the background tracing manager, which allows it to install UMA callbacks in child processes, and trigger background tracing from there.
BUG=504889
