Some specifics of machine types may depend on the accelerator and thus
the data should be moved to virQEMUCapsAccel. The TCG machine types are
just copied from the ones probed for KVM to simplify the changes to
qemucapabilitiestest data files.

The function would return a valid virDomainCapsCPUModelsPtr with empty
CPU models list if query-cpu-definitions exists in QEMU, but returns
GenericError meaning it's not in fact implemented. This behaviour is a
bit strange especially after such virDomainCapsCPUModels structure is
stored in capabilities XML and parsed back, which will result in NULL
virDomainCapsCPUModelsPtr rather than a structure containing nothing.
Let's just keep virDomainCapsCPUModelsPtr NULL if the QMP command is not
implemented and change the return value to int so that callers can
easily check for failure or success.

Rather than returning a direct pointer the list stored in qemuCaps the
function now creates a new copy of the CPU models list.
The main purpose of this seemingly useless change is to update callers
to free the result returned by virQEMUCapsGetCPUDefinitions because the
internals of this function will change significantly in the following
patches.
