Add diagnostic for invalid linking compile option

[Sergio0694]

Description

There currently is no diagnostic if a shader is compiling with linking support where that's definitely not supported.

Rationale

Flagging this can reduce the size of the compiling shader, as the option is not needed anyway. This should only apply to when the option is used manually on a single shader, and not when it's inherited by a global configuration.

Example

[D2DInputCount(1)]
[D2DInputComplex(0)]
[D2DRequiresScenePosition]
[D2DShaderProfile(D2D1ShaderProfile.PixelShader40)]
[D2DCompileOptions(D2D1CompileOptions.EnableLinking)]
public partial struct MyShader : ID2D1PixelShader
{
    // ...
}

Should generate a diagnostic.
