Expose virtual_camera types

virtual_camera uses GPU to render data into a surface and requries
access to some GPU sysfs node.

Since vendor defines their own sysfs node with a label different from
the one in AOSP, we need to expose the virtual_camera domain in the
public policy to allow vendor to extend the rules (similar to
cameraserver)
