Split along `dim` into chunks of the given lengths; `sizes` must sum to the dim's extent. Each length is a literal or a 0-D integer [Tensor](../Tensor.md).

Returns VIEWS; every chunk shares the source's storage (no copy).

**Throws**

- `ClikaRT::Error`: (`INVALID_ARGUMENT`) when the sizes do not sum to the dim's extent (`code_name()` carries the reason).

**Returns:** one view per requested chunk.

```cpp
auto qkv = ClikaRT::ops::split_with_sizes(fused, {dq, dk, dv}, -1);
```
