fix[react-devtools]: add backwards compat with legacy element type symbol (#28982)

Follow-up to https://github.com/facebook/react/pull/28813.

RDT is using `typeOf` from `react-is` to determine the element display
name, I've forked an implementation of this method, but will be using
legacy element symbol.
