We've heard from multiple contributors that the Reconciler forking
mechanism was confusing and/or annoying to deal with. Since it's
currently unused and there's no immediate plans to start using it again,
this removes the forking.
Fully removing the fork is split into 2 steps to preserve file history:
**#25774 previous PR that did the bulk of the work:**
- remove `enableNewReconciler` feature flag.
- remove `unstable_isNewReconciler` export
- remove eslint rules for cross fork imports
- remove `*.new.js` files and update imports
- merge non-suffixed files into `*.old` files where both exist
(sometimes types were defined there)
**This PR**
- rename `*.old` files

* Facebook -> Meta in copyright
rg --files | xargs sed -i 's#Copyright (c) Facebook, Inc. and its affiliates.#Copyright (c) Meta Platforms, Inc. and affiliates.#g'
* Manual tweaks
* Use consistent naming for unstable_testing entry point
* Exclude the testing build from non-experimental builds except at FB
* FB builds shouldn't contribute to whether we include the npm files
* Exclude exports fields if we delete the files entry
* Move test to no longer be internal so we can test against the build
* Update the bundle artifact names since they've now changed
* Gate import since it doesn't exist
