[PATCH vkd3d 5/6] vkd3d-shader: Avoid declaring outputs multiple times with incompatible types.

[Henri Verbeet]

This would cause CoreValidation-Shader-InterfaceTypeMismatch validation
errors from Wine's test_shader_interstage_interface() d3d11 test. This
reverts parts of commits 1eb7eca411f71d8dec7cfae5c58c1dff9626a7e0 and
04ec461fb4224e126d271760123bb6d756c06582.
