qemu: Move and rename qemuDomainUpdateQEMUCaps

Browse Source 
The function is now used only in qemu_process.c so move it there and
name it 'qemuProcessPrepareQEMUCaps' which is more appropriate to what
it's doing.

The reworded comment now mentions that it will also post-process the
caps for VM startup.
