Add Combobox component (#1047)

* start of combobox

* start with a copy of the Listbox

* WIP

* Add Vue Combobox

* Update Vue version of combobox

* Update tests

* Fix typescript errors in combobox test

* Fix input label

The spec says that the combobox itself is labelled directly by the associated label. The button can however be labelled by the label or itself.

* Add active descendant to combobox/input

* Add listbox role to comobox options

Right now the option list *is* just a listbox. If we were to allow other types in the future this will need to be changable

* Update tests

* move React playground to dedicated package

* add react playground script to root

* ensure we only open/close the combobox when necessary

* ensure export order is correct

* remove leftover pages directory from React package

* Only add aria controls when combobox is open

* add missing next commands

* make typescript happy

* build @headlessui/react before building playground-react

* add empty public folder

This makes vercel happy

* wip

* Add todo

* Update tests

Still more updates to do but some are blocked on implementation

* change default combobox example slightly

* ensure that we sync the input with new state

When the <Combobox value={...} /> changes, then the input should change
as well.

* only sync the value with the input in a single spot

* WIP: object value to string

* WIP

* WIP

* WIP groups

* Add static search filtering to combobox

* Move mouse leave event to combobox

* Fix use in fragments

* Update

* WIP

* make all tests pass for the combobox in React

* remove unnecessary playground item

* remove listbox wip

* only fire change event on inputs

Potentially we also have to do this for all kinds of form inputs. But
this will do for now.

* disable combobox vue tests

* Fix vue typescript errors

* Vue tests WIP

* improve combobox playgrounds a tiny bit

* ensure to lookup the correct value

* make sure that we are using a div instead of a Fragment

* expose `activeItem`

This will be similar to `yourData[activeIndex]`, but in this case the
active option's data. Can probably rename this if necessary!

* Update comments

* Port react tests to Vue

* Vue tests WIP

* WIP

* Rename activeItem to activeOption

* Move display value to input

* Update playgrounds

* Remove static filtering

* Add tests for display value

* use correct event

* use `let` for consistency

* remove unnecessary hidden check
