This update was a bit more involved.
- `React$Component` was removed, I replaced it with Flow component
types.
- Flow removed shipping the standard library. This adds the environment
libraries back from `flow-typed` which seemed to have changed slightly
(probably got more precise and less `any`s). Suppresses some new type
errors.
These used to be used by partial render.
ReactDOMDispatcher ended up not being used in this way.
Move shared DOM files to client. These are only used by client
abstractions now. They're inlined in the Fizz code so they're no longer
shared.

This lets us share it with react-server-dom-webpack while still having a
dependency on react-dom. It also makes somewhat sense from a bundling
perspective since react-dom is an external to itself.
