microsoft/compiler: Set typed_uav_load_additional_formats when appropriate

This flag should be set to true when the RWTexture is attached a vector,
and we always declare a vec4 right now, so it should always be true.
Might be worth reworking the dxil_module_get_res_type() to use a scalar
when the image only has one component.
