Summary:
The `Systrace` module implements a polyfill for the User Timing API that's:
1. Incompatible with the Web standard. This polyfill expects `performance.mark` and `performance.measure` to be used exactly like `Systrace.beginEvent` and `Systrace.endEvent` respectively. If not used like those functions, they throw an error at runtime, which is really bad.
2. Never actually used. See below.
This polyfill is only installed if we're actually profiling on startup:
https://www.internalfb.com/code/fbsource/[4d888a933920]/xplat/js/react-native-github/Libraries/Core/setUpSystrace.js?lines=17-21
While the only code that we have that uses this API is actually not installed if we're profiling:
https://www.internalfb.com/code/fbsource/[4d888a933920]/xplat/js/react-native-github/Libraries/Core/setUpDeveloperTools.js?lines=20-21
This should be safe to remove then.
We have plans to add proper support for this API in the short term, so this also gets out of the way of doing that.
Additionally, installing this polyfill was the only reason why we had `setupSystrace`, so we can get rid of that too :)

Summary:
This diff runs the codemod to add type annotations to function parameters in preparation for Flow's local type inference (LTI) project. I ran the codemod over xplat/js and reverted any files that had flow errors in them. See the list of commands run to see the regeneration of various files.
Changelog:
[Internal][Changed] - Added type annotations

Summary:
The `Systrace` and `Refresh` dependencies are injected into the `metroRequire` implementation by assigning the values to e.g. `require.Systrace = ...`.
The issue with this approach is that some `require` implementations might not support extending the `require` object or doing so results in a degraded performance. An example where this is the case is Hermes where changing the `require` object forces Hermes to opt out of the static require optimization.
This diff extends Metro so that the `Systrace` and `Refresh` implementation can either be injected by assigning to `require.Systrace` or by exposing the implementation in the global scope. It further changes the `Systrace` and `Refresh` modules to inject the instances using the global scope instead of extending `require`.
Changelog:
[Internal][Changed] - Expose Systrace and ReactRefresh as globals instead of extending require.

Summary: This is one more step to remove `fbjs` from `react-native-github`. This changes both the internal and external code to use `invariant` from zertosh instead of the copy in fbjs.

Summary:
This PR removes the need for having the `providesModule` tags in all the modules in the repository.
It configures Flow, Jest and Metro to get the module names from the filenames (`Libraries/Animated/src/nodes/AnimatedInterpolation.js` => `AnimatedInterpolation`)
* Checked the Flow configuration by running flow on the project root (no errors):
```
yarn flow
```
* Checked the Jest configuration by running the tests with a clean cache:
```
yarn jest --clearCache && yarn test
```
* Checked the Metro configuration by starting the server with a clean cache and requesting some bundles:
```
yarn run start --reset-cache
curl 'localhost:8081/IntegrationTests/AccessibilityManagerTest.bundle?platform=android'
curl 'localhost:8081/Libraries/Alert/Alert.bundle?platform=ios'
```
[INTERNAL] [FEATURE] [All] - Removed providesModule from all modules and configured tools.
