[Select][Menu] Better handle dynamic and non-string items

[atomiks]

• Select: Fixes #1853 to ensure non-string values don't warn, clears styles and scroll arrows state when the item list size changes
• Select: Fixes #1922 to ensure the selectedItemTextRef.current is set when the previous text element gets disconnected, fixing the positioning
• Select + Menu: Fixes focus restoration (add restoreFocus prop) to ensure keyboard navigation works when item is removed while menu is open
• Select: Fixes error due to scrollArrow visibility state changing state of parent component in render by moving it locally
