qemu_monitor: add features to CPU model for QMP command

Browse Source 
query-cpu-model-baseline/comparison will accept a list of features
as part of the command. Since CPUs may be defined with CPU feature
policies, let's parse it to the appropriate boolean that the QMP
command expects.

A feature that is set to required, force, or if it is a hypervisor
CPU feature (-1), then set the property value to true. Otherwise
(optional, disabled) set the value to false.
