Subject: [PATCH] dialects: (csl) set_tile_code fix traits

`set_tile_code` does not have to be a direct child of `layout`, e.g. it can
be used in a loop. But it does have to occur in a `layout`.

_NOTE_: the parameter to `set_tile_code` is specified as
`ComptimeStructType`, not `StructLike`. This is semantically correct
(though undocumented), i.e. you can't do this:

```zig
const my_params = @import_module("my_params.csl")
...
@set_tile_code(..., my_params);
```

Not that this is likely to happen.
