Fix Dropdown useMemo not detecting equal objects

[mariusdkm]

This pull requests improves the performance of the dash core component dropdown.
The useMemo didn't recognize that the objects inside the options array of the dropdown stayed the same, so the useMemo got recalculated all the time.
Because of this Dropdowns with a lot of values inside (I have some with >1k) took a lot of time to render(>100ms).
Using the useRef the current options-object(and the address associated with that) are saved and compared with the new options-object is deep compared to that one using isEqual from react-fast-compare.
That way the persistentOptions is only changed when the options change, and that way the useMemo is only executed when needen.
