Sort icon
**Describe the requested icon(s)**
Would love to see an icon that would go along well with the `sort-ascending` and `sort-descending` icons. This would be an icon that would be used when nothing is currently being sorted, so an initial state. I don't think the current filter/funnel icons cover the use case.

**References**
Here's a quick idea I put together using existing phosphor iconography. Also included an example from material as an example.

**Additional context**
I'm not expecting it to be exactly as I suggested. If including a double arrow or something like that fits the phosphor look and feel better, that's great too. I think the `sort-ascending` and `sort-descending` icons are great, but I need an initial state for columns that can be sorted but haven't been yet.
