The reworked API is now called virCPUUpdate and it should change the
provided CPU definition into a one which can be consumed by QEMU command
line builder:
- host-passthrough remains unchanged
- host-model is turned into custom CPU with a model and features
copied from host
- custom CPU with minimum match is converted similarly to host-model
- optional features are updated according to host's CPU
