fix(combobox): memoize floating ui ref to prevent max call depth

[tay1orjones]

Closes #16857

This PR does to primary things:

1. Memoize the value of getMenuProps to avoid an infinite loop
2. Only apply floating ui refs when autoAlign={true}

The first fixes the problem outlined in the original issue, the second is an indirect improvement. If the refs had initially been guarded, this bug would've been isolated to users using autoAlign. Because the refs were not guarded, the bug was present for everyone regardless of if autoAlign was being used.

From what I can tell, there is not a reliable way to unit test this as the keyboard entry rate isn't configurable.

Changelog

Changed

• Wrap getMenuProps in useMemo
• Conditionally apply refs

Testing / Reviewing

• Go to the default combobox story. Type super fast - like just totally spam the keyboard. The component should not error
• Do the same on the allowCustomInput combobox story
• Do the same on the with experimental autoalign combobox story
• Ensure autoAlign works as expected on combobox by resizing the browser window, playing with scroll, and opening/closing the listbox
