vkd3d-shader/spirv: Handle VSIR_DATA_MIXED in spirv_get_type_id().

Browse Source 
For example, a HLSL shader like this:

    tbuffer t0
    {
        float4 data;
    };

    float4 main() : sv_target
    {
        return data;
    }

would be compiled to the following:

    ps_4_0
    dcl_resource_buffer (mixed,mixed,mixed,mixed) t0
    dcl_output o0.xyzw
    dcl_temps 1
    ld r0.xyzw, l(0, 0, 0, 0), t0.xyzw
    mov o0.xyzw, r0.xyzw
    ret

VSIR_DATA_MIXED used to be mapped to VKD3D_SHADER_COMPONENT_UINT by
vkd3d_component_type_from_data_type(), but we no longer use that.
