It is expected this diff will individually fail. The entire stack should be applied at once.

Summary:
`VirtualizedList_EXPERIMENTAL` is a fork of VirtualizedList. It was originally created for the purpose of keyboard/a11y fixes, which required the list to allow rendering discontiguous regions of cells. So, the large part of the refactor is in the data structure used to represent state (now a sparse bitmask), and building out the render function to operate off the bitmask.
This structure allows pre-rendering areas where we know focus must be able to be synchronously be moved to. This is exercised on platforms like Windows and macOS which fire view level focus events. The new implementation otherwise aims to preserve near-exact list behavior as previously.
Apart from the structure change, the refactor has made the code (subjectively) a lot easier to reason about, and there are now stronger internal invariants than before. The bitmask structure also enables new approaches for nested list stability, and implementing OffScreen.
**Why ship it now?**
Having two implementations has multiple times prevented other changes to VirtualizedList, so it is incurring a constant engineer cost.
At this point, we have a lot of reason to be confident in the maturity of the new list implementation (see the test plan below). So, reconciling the implementations not only unlocks the enhancements of the new list, but unblocks future changes to VirtualizedList.
## Test Plan
1. **Unit tests:** A few dozen unit tests were added to VirtualizedList, validating the regions it renders in response to injected input, across its API surface. Both VirtualizedList implementations must pass the same tests, around expected behavior.
2. **RNTester:** Scenarios in RNTester were manually validated, and all worked as before
3. **New invariants:** I added a lot of internal logic checks and bounds checks as invariant violations, to try to produce signal if any part of the refactor went unexpected in the wild.
4. **MSFT Rollout:** I rolled out the changes as a fork of VirtualizedList at MSFT to a couple of high-usage surfaces using Android, iOS, and Windows on Paper. Some invariant violations were surfaced and fixed, but telemetry showed solid system and scenario health with the change.
5. **Meta import:** Fixed all land-blocking test failures when using the new list. These were confined to updating snapshots, and adding additional checks for invalid input.
6. **Panel apps:** Manually validated top-level surfaces of panel apps in debug/release modes. Fixed a couple of invariant violations and novel usages. Profiled new JS structures against an expensive list with Hermes profiler.
7. **Facebook App Rollout:** After some manual validation of top-level surfaces, the change was rolled out to Facebook for Android and iOS as an experiment. New invariant violations were fixed, and the change has sat in production for several weeks at this point, while measuring impact to metrics like error rate, responsiveness, and impressions.
This is the first introduction to all of OSS, and some Meta internal apps. This means there may still be novel usages of VirtualizedList that were not picked up during testing, but I think there has been enough diligence to roll out what has been tested, and forward fix anything unexpected that might still come up.

We are in the middle of a Prettier upgrade and some of the files which disagree between Prettier v1.x and v2.x are now being flagged by `eslint-plugin-prettier` as lint errors.
The correct fix here is probably to update `eslint-config-prettier` and `eslint-plugin-prettier`, but I am landing this first to unbreak CI.

Summary:
This was all yungsters idea. I blame him. :)
Switching Pressable to be a functional component presents a new challenge. ReactNativeTestTools can no longer find its instance because there is no instance Pressable uses forwardRef.
We need a way to both find a pressable, and then call the onPress callback if the pressable isn't also disabled.
So in DEV (and thus test) we add the pressable config to a secret key on a function passed onto View. The TestTools look for this key on this function, and then can call onPress.
Super hacky, but so is all of ReactNativeTestTools. We aren't proud of this.

Summary:
This is the next step in moving RN towards standard path-based requires. All the requires in `Libraries` have been rewritten to use relative requires with a few exceptions, namely, `vendor` and `Renderer/oss` since those need to be changed upstream. This commit uses relative requires instead of `react-native/...` so that if Facebook were to stop syncing out certain folders and therefore remove code from the react-native package, internal code at Facebook would not need to change.

Summary:
Modified the ESLint configuration to only enable the Jest environment for files we consider now tests, which are files with the `-test.js` suffix under `__tests__`. Also enabled some globals for test helpers (any file under `__tests__`).
This will allow us to catch misspelled tests, while allowing test helpers to use most Jest APIs.
Also disabled the Jasmine environment so people stop using Jasmine APIs and we can rollout Circus soon.

Back it out again. This time really not sure why this is breaking, but it seems to be production only. The error seems to be "RCTSinglelineTextInputView" was not found in the UIManager" but the relavent logic is not changed in this diff, just moved around, so unclear why it would trigger a failure.
Reverting to be safe. When we re-apply the diff, we'll need to test a full OTA to prod to verify the fix.
