kvm: allow target-specific accelerator properties

Several hypervisor capabilities in KVM are target-specific.  When exposed
to QEMU users as accelerator properties (i.e. -accel kvm,prop=value), they
should not be available for all targets.

Add a hook for targets to add their own properties to -accel kvm, for
now no such property is defined.
