This CL enhances the --utility-startup-dialog switch to now take an
optional service sub type, and displays the subtype when waiting
for the debugger, or showing the dialog.
`chrome --utility-startup-dialog` works as before, prompting/pausing
for every utility process.
`chrome --utility-startup-dialog=data_decoder.mojom.DataDecoderService`
only prompts for the data decoder service.
We check for the switch first then interrogate its value to limit
any impact on normal startup time.
This should make it easier to debug specific utility processes.
Tests: manual tested on Windows & Linux
