Bill Currie c1b85a3db7 [vkgen] Support custom parsing in multi-type fields
This allows the likes of:

    qfv_pushconstantrangeinfo_s = {
	.name = qfv_pushconstantrangeinfo_t;
	.type = (QFDictionary);
	.dictionary = {
	    .parse = {
		type = (labeledarray, qfv_pushconstantinfo_t, name);
		size = num_pushconstants;
		values = pushconstants;
	    };
	    stageFlags = $name.auto;
	};
	stageFlags = auto;
    };

Leading to:

    pushConstants = {
	vertex   = { Model = mat4; blend = float; };
	fragment = { colors = uint; base_color = vec4; fog = vec4; };
    };

Where the label of the labeled array (which pushConstants is) is
actually an enum flag and the dictionary value is another labeled array.
