sl-input does not support list attribute

[Diegovsky]

Describe the bug

Sl-Input should support the list attribute but it appears not to.

To Reproduce

Steps to reproduce the behavior:

1. Create datalist element with options inside whose id is datalist.
2. Create a sl-input element whose list attribute is datalist.
3. Try to have any autocomplete by selecting the input.

Additional information

It would be nice if shoelace forwarded not explicitly used attributes straight to the input tag.

[KonnorRogers]

Forwarding won't work.

We would need to explicitly clone the datalist from the light dom into the shadow dom.

There's some further discussion here:
