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

[EAlexRojas]

Closes #17001

Applies similar approach as for the Combobox component (in #16866) to memoize the value of getMenuProps to avoid an infinite loop.

Changelog

Changed

• Wrap getMenuProps in useMemo
• Conditionally apply refs

Testing / Reviewing

• Go to default dropdown story. Verify there is no regression for default behaviour.
• Ensure autoAlign works as expected on dropdown by resizing the browser window, playing with scroll, and opening/closing the listbox
• The original issue only appeared when running cypress tests, only way to validate this fixes the bug in that case would be to add a cypress test for the Dropdown component.

Note: The fix was validated in an existing app by applying a patch.

Thanks for catching this, submitting the fix, and testing it! Since it's so close to that other PR and you've said it fixes your test case, I think this looks good to merge
