The most operational definition is that a content process is a process
where XRE_IsContentProcess() returns true. From the enum GeckoProcessType,
you can see the various other possibilities. So the answers to your
questions are then probably that GMP and GPU are not, but the others are.
Though maybe you are asking which processes count against the limit of 4.
