s390x/cpumodel: register defined CPU models as subclasses
This patch adds the CPU model definitions that are known on s390x - like z900, zBC12 or z13. For each definition, introduce two CPU models: 1. Base model (e.g. z13-base): Minimum feature set we expect to be around on all z13 systems. These models are migration-safe and will never change. 2. Flexible models (e.g. z13): Models that can change between QEMU versions and will be extended over time as we implement further features that are already part of such a model in real hardware of certain configurations. We want to work on features using ordinary bitmap operations, however we can't initialize a bitmap statically (unsigned long[] ...). Therefore we store the generated feature lists in separate arrays and convert them to proper bitmaps before registering all our CPU model classes.
