Summary:
* Removed Flow compilation step
* Removed all `flow` annotations
* Removed all FlowFixMe's
* Removed flow typings for Flipper
* Left flow transpilation (stripping) in babel, in case there is any external user using Flow in his plugin
* Left `eslint-plugin-flowtype` dependencies, as `eslint-config-fbjs` requires it

Summary:
Quick notes:
- This looks worse than it is. It adds mandatory parentheses to single argument lambdas. Lots of outrage on Twitter about it, personally I'm {emoji:1f937_200d_2642} about it.
- Space before function, e.g. `a = function ()` is now enforced. I like this because both were fine before.
- I added `eslint-config-prettier` to the config because otherwise a ton of rules conflict with eslint itself.
