Dan Abramov c080537a7b Flatten the shared/ folder (#11297)
* shared/src -> shared

It's not a real package and doesn't even have package.json.
This will also make importing less weird if we drop Haste.

* Get rid of shared/utils

Moved event-specific into shared/event.
Moved rest to the root since distinction has always been pretty arbitrary.

* Fix references to old shared/src paths
