Feat/react aria components

[Jonesus]

Reimplements a few UIKit components with react-aria-components

Commits should be quite clear for review, and changes easily testable in storybook

---

• Now includes label as a prop that will render it on the right side of the checkbox
• Optionally, labelledby can be passed if only a checkbox without visible label is required
• Adds indeterminate as a state, useful for example for a "select all" checkbox on a table with only some rows checked

---

• Styling changed a bit from floating label to a static one above the input box
  • Moving label is difficult from a11y perspective, as we would need to disable and move it to final position if user has prefers-reduced-motion
  • Placeholders don't work that cleanly with floating label
  • Me and Otto like the looks of this one better :stuck_out_tongue_winking_eye:
• Error state styled a bit differently
  • error instead of warn color
  • Includes a warning triangle so that error message can be differentiated from an input description
• Description and error can be shown simultaneously

---

• Reuses stylings from TextInput
• Popover list and options can be styled
  • Distinct styling for currently selected option and focused/hovered option
  • Can be bikeshed indefinitely :stuck_out_tongue:
• Rename prop options -> items to mimic defaults of react-aria(-components)

---

• Newly implemented
• Shared styles with Select

Now it should be good by me, do you want a final check or just :ship: ?
