benchmark: Define exit points and values
Benchmarking IO port addresses and return values are now defined
through a dedicated header.
Each exit point can have its own IO port address and return value.
With this we are able to discriminate between similar code paths
through the QEMU process return values or between different
code paths by having the QEMU debugexit device monitoring
different IO port addresses.
