A new tensor with `input`'s shape and dtype, every element set to `value`.

`input` supplies GEOMETRY only; its data is never read. `value` is a literal or a 0-D [Tensor](../Tensor.md) (a tensor value traces symbolically).

**Parameters**

- `input`: shape/dtype donor.
- `value`: the fill value, cast to `input`'s dtype.
- `device`: optional stream override. Default: `input`'s placement.

**Throws**

- `ClikaRT::Error`: when the input's dtype is not served for this operation (the machine-readable reason rides `code_name()`).

**Returns:** a new tensor shaped like `input`, filled with `value`.
