bhyve: add VNC password support

Support setting a password for the VNC framebuffer using the passwd
attribute on the <graphics/> element, if the driver has the
BHYVE_CAP_VNC_PASSWORD capability.

Note that virsh domxml-from-native does not output the password in the
generated XML, as VIR_DOMAIN_DEF_FORMAT_SECURE is not set when
formatting the domain definition.

Libvirt can now set the framebuffer's "w" and "h" parameters
using the ``resolution`` element.
* bhyve: Support VNC password authentication
Libvirt can now probe whether the bhyve binary supports
VNC password authentication. In case it does, a VNC password
can now be passed using the ``passwd`` attribute on
the ``<graphics>`` element.
* **Improvements**
