config_tools: track whether each vCPU is used for real-time or not

Browse Source 
According to DX recommendations, this patch adds a Boolean item to each
vCPU which allows users to specify the vCPUs intended for
real-time-critical tasks. This information will be used to organize other
widgets (CAT-related ones for now) in the configurator to tell apart
real-time ones from the others for better clarity.

All vCPUs are by default not real-time-critical, except those in the RT VMs
which are.
