Let's see if this lets us reclaim some of the byte increase from #20760.

The idea is that for an overwhelming majority of events, the DOM name is just the lowercase version of the React name without the on before it. We already do some string acrobatics to get the React name, so why not reuse them and remove the repetition of almost the same term. This was a bit harder to do before because this list was also used for priorities, but it's not anymore. I hardcoded the exceptions.

Note I added tests for all of these events in ReactDOMEventPropagation-test.js a while ago so we should be safe.
