vkd3d-shader/d3d-asm: Use vkd3d_shader_register.dimension to know when to dump writemask.

This change ensures that we don't dump the writemask for registers that
have a scalar dimension.

For instance, for this shader:

    float r;

    float4 main(out float d : DEPTH) : sv_target
    {
        d = r;
        return 0;
    }

we now correctly dump

    dcl_output oDepth

instead of

    dcl_output oDepth.x
