Use Yarn Workspaces (#11252)

* Enable Yarn workspaces for packages/*

* Move src/isomorphic/* into packages/react/src/*

* Create index.js stubs for all packages in packages/*

This makes the test pass again, but breaks the build because npm/ folders aren't used yet.
I'm not sure if we'll keep this structure--I'll just keep working and fix the build after it settles down.

* Put FB entry point for react-dom into packages/*

* Move src/renderers/testing/* into packages/react-test-renderer/src/*

Note that this is currently broken because Jest ignores node_modules,
and so Yarn linking makes Jest skip React source when transforming.

* Remove src/node_modules

It is now unnecessary. Some tests fail though.

* Add a hacky workaround for Jest/Workspaces issue

Jest sees node_modules and thinks it's third party code.

This is a hacky way to teach Jest to still transform anything in node_modules/react*
if it resolves outside of node_modules (such as to our packages/*) folder.

I'm not very happy with this and we should revisit.

* Add a fake react-native package

* Move src/renderers/art/* into packages/react-art/src/*

* Move src/renderers/noop/* into packages/react-noop-renderer/src/*

* Move src/renderers/dom/* into packages/react-dom/src/*

* Move src/renderers/shared/fiber/* into packages/react-reconciler/src/*

* Move DOM/reconciler tests I previously forgot to move

* Move src/renderers/native-*/* into packages/react-native-*/src/*

* Move shared code into packages/shared

It's not super clear how to organize this properly yet.

* Add back files that somehow got lost

* Fix the build

* Prettier

* Add missing license headers

* Fix an issue that caused mocks to get included into build

* Update other references to src/

* Re-run Prettier

* Fix lint

* Fix weird Flow violation

I didn't change this file but Flow started complaining.
Caleb said this annotation was unnecessarily using $Abstract though so I removed it.

* Update sizes

* Fix stats script

* Fix packaging fixtures

Use file: instead of NODE_PATH since NODE_PATH.
NODE_PATH trick only worked because we had no react/react-dom in root node_modules, but now we do.

file: dependency only works as I expect in Yarn, so I moved the packaging fixtures to use Yarn and committed lockfiles.
Verified that the page shows up.

* Fix art fixture

* Fix reconciler fixture

* Fix SSR fixture

* Rename native packages
