COMPMID-1021: CPUInfo refactoring.
Removed CPUTarget in favor of the CPUModel type. CPUInfo now holds a vector of N CPUs. CPUInfo autoinitialise upon construction with 1 GENERIC CPU. CPPScheduler fills CPUInfo's vector upon construction (runtime). IScheduler has a single CPUInfo obj and ThreadInfo always gets a pointer to it (avoid copying the vector) Change-Id: I30f293258c959c87f6bac5eac8b963beb6a4d365 Reviewed-on: https://eu-gerrit-1.euhpc.arm.com/124626 Tested-by: Jenkins <bsgcomp@arm.com> Reviewed-by: Anthony Barbier <anthony.barbier@arm.com>
