Hook names grabbing solution w/o changing api

[a-x-]

add to react jsx babel transformation minor version with grabber assosiated with hooks const names.

It's dead easy, I can create a demo.

const [data, updData] = useState(null);

would be something like:

const [data, updData] = useState(null);
__devtools_reportHookName(data, 'data'); // data is a pointer to some Map storage under the hook of devtools
