Upgrade to Jest 25

Summary:
This diff upgrades Jest to the latest version which fixes a bunch of issues with snapshots (therefore allowing me to enable the Pressable-test again). Note that this also affects Metro and various other tooling as they all depend on packages like `jest-worker`, `jest-haste-map` etc.

Breaking changes: https://github.com/facebook/jest/blob/master/CHANGELOG.md

This diff increases node_modules by 3 MiB, primarily because it causes more duplicates of `source-map` (0.8 MiB for each copy) and packages like `chalk` 3.x (vs 2.x). The base install was 15 MiB bigger and I reduced it to this size by playing around with various manual yarn.lock optimizations. However, D21085929 reduces node_modules by 11 MiB and the Babel upgrade reduced node_modules by 13 MiB. I will subsequently work on reducing the size through other packages as well and I'm working with the Jest folks to get rid of superfluous TypeScript stuff for Jest 26.

Other changes in this diff:
* Fixed Pressable-test
* Blackhole node-notifier: It's large and we don't need it, and also the license may be problematic, see: jestjs/jest#8918
* Updated jest-junit (not a Jest package) but blackholed it internally because it is only used for open source CI.
* Updated some API calls we use from Jest to account for breaking changes
* Made two absolutely egrigious changes to existing product code tests to make them still pass as our match of async/await, fake timers and then/promise using `setImmediate` is tripping up `regenerator` with `Generator is already run` errors in Jest 25. These tests should probably be rewritten.
* Locked everything to the same `resolve` version that we were already using, otherwise it was somehow pulling in 1.16 even though nothing internally uses it.
