Tooltip component

[paigely]

I'd like to see a Tooltip component with M3 styling included in this, I'm not really sure what a good API for this could be, but it could potentially be something like this:

<script>
    import { Tooltip } from "m3-svelte";
</script>

<Tooltip text="something">
    <p>something with a tooltip</p>
</Tooltip>

Sliders already have tooltips, so it would be nice if we could just use their tooltips:

fwiw sliders' "tooltips" are different from real tooltips

@mrsproutt aren't you working on this?

Yep! The api even works exactly like the issue described, but only implements plain tooltips. https://github.com/mrsproutt/m3-svelte/tree/tooltips
