I'm trying to get rid of all meta programming in the module scope so
that closure can do a better job figuring out cyclic dependencies and
ability to reorder.
This is converting a lot of the patterns that assign functions
conditionally to using function declarations instead.
```
let fn;
if (__DEV__) {
fn = function() {
...
};
}
```
->
```
function fn() {
if (__DEV__) {
...
}
}
```
## Summary
- yarn.lock diff +-6249, **small pr**
- use jest-environment-jsdom by default
- uncaught error from jsdom is an error object instead of strings
- abortSignal.reason is read-only in jsdom and node,

## How did you test this change?

The old version of prettier we were using didn't support the Flow syntax
to access properties in a type using `SomeType['prop']`. This updates
`prettier` and `rollup-plugin-prettier` to the latest versions.
I added the prettier config `arrowParens: "avoid"` to reduce the diff
size as the default has changed in Prettier 2.0. The largest amount of
changes comes from function expressions now having a space. This doesn't
have an option to preserve the old behavior, so we have to update this.

Moves the unit testing library for events into the `packages` directory so it can more easily be used in tests for other react packages, and mirrored internally to help with testing of event hooks we prototype in www.
