[poc] Add FloatingPopup

[mj12albert]

Preview:

• Autocomplete
• Tooltip

Provides FloatingPopup (uses Floating UI) as an opt-in replacement for Popper, since PopperJS is deprecated.

Usage:

<Autocomplete
  slots={{
    popper: FloatingPopup,
  }}
/>

<Tooltip
  slots={{
    popper: FloatingPopup,
  }}
/>

Bundle size reduction of swapping out popper entirely: 7KB gz (@popperjs/core) - @floating-ui/dom 4.5KB gz = 3KB gz. The downside is if you only swap out one instead of both you'll have both deps 😓

• I have followed (at least) the PR section of the contributing guide.
