Remove --trace-all-rendered-frames in favour of disabled-by-default.

With this CL the trace events that were previously behind the
--trace-all-rendered-frames will now be available through the trace-event
UI as disabled-by-default elements. They will only show up in the trace
files if explicitly selected in the tracing UI.
