Add a quick trigger action to the Menu, Listbox and Combobox components (#3700)

This PR adds a new quick trigger feature to the `Menu`. Not sure what the best name for this is, but essentially this is the behavior: Recently we made sure that the `Menu` opens on `mousedown` (not just `click`). This means that we can perform the following quick action: 1. `mousedown` on the `MenuButton` — this will open the `Menu` 2. Without releasing the mouse button yet, move your mouse over one of the `MenuItem`s — this will highlight the currently active `MenuItem`. 3. Release the mouse button — this will invoke the currently active `MenuItem` and close the `Menu`. This now means that you can perform actions very quickly. What this PR doesn't do yet is if you have a scrollable list, then it won't scroll up or down when you reach the ends of the list. For this we would need to introduce some new elements. The native Menu items on macOS show a little placeholder arrow. If you put your cursor in that area, it starts scrolling: <img width="489" alt="image" src="https://github.com/user-attachments/assets/e3a90d5a-daa7-4711-9e19-050578be3e02" /> ## Test plan 1. Everything still works as expected 2. Quick release has been added: - Listbox: https://headlessui-react-git-feat-quick-trigger-tailwindlabs.vercel.app/listbox/listbox-with-pure-tailwind - Menu: https://headlessui-react-git-feat-quick-trigger-tailwindlabs.vercel.app/menu/menu - Combobox: https://headlessui-react-git-feat-quick-trigger-tailwindlabs.vercel.app/combobox/combobox-countries
