Include inout cast operation as an aliasing instruction (#4859)

Previously, the warnings were:

```
environment.slang(22): warning 41022: inout parameter 'seed' is never written to
public float3 environment_sample(StructuredBuffer <Environment_sample_data> sample_buffer, inout int seed)
              ^~~~~~~~~~~~~~~~~~
hit.slang(5): warning 41022: inout parameter 'seed' is never written to
float3 sample_lights(inout uint seed)
       ^~~~~~~~~~~~~
```

With this commit they should not be emitted.
