## Summary
Mostly changing the casting syntax from `(x: Y)` to `x as Y`, as the old
syntax was deprecated and always causing an error in Flow
## How did you test this change?
`yarn flow-ci`
We're currently hardcoding experimental options to
`eslint-plugin-react-hooks`. This blocks the release on features that
might not be ready.
This PR extends the ReactFeatureFlag infra to support flags for
`eslint-plugin-react-hooks`. An alternative would be to create a
separate flag system for build tools, but for now we have a small number
of these and reusing existing infra seems like the simplest approach.
I ran a full `yarn build` and checked the output resolved the flag
values as expected:
_build/oss-stable-semver/eslint-plugin-react-hooks/cjs/eslint-plugin-react-hooks.development.js_
```js
var eprh_enableUseKeyedStateCompilerLint = false;
var eprh_enableVerboseNoSetStateInEffectCompilerLint = false;
var eprh_enableExhaustiveEffectDependenciesCompilerLint = 'off';
```
_build/facebook-www/ESLintPluginReactHooks-dev.classic.js_
```js
var eprh_enableUseKeyedStateCompilerLint = true;
var eprh_enableVerboseNoSetStateInEffectCompilerLint = true;
var eprh_enableExhaustiveEffectDependenciesCompilerLint = 'extra-only';
```

Added the standard Meta Platforms, Inc. MIT license notice to the top of
the feature flag comparison script to ensure compliance with repository
licensing requirements and for code consistency.
**No functional or logic changes were made to the code.**
The `__NEXT_MAJOR__` value in the RN flags doesn't make sense because:
a) The flags are for the next RN major, since it only impacts the
renderers
b) The flags are off, so they're not currently in the next major, they
need enabled
c) the flag script didn't support it
This PR adds two aliases to the RN file:
- `__TODO_NEXT_RN_MAJOR__`: flags that need enabled before the next RN
major.
- `__NEXT_RN_MAJOR__`: flags that have been enabled since the last RN
major.
These values will need to be manually kept up to date when we cut a RN
version, but once RN switches to the canary build and aligns all the
flags, this entire file can be deleted.
## Script screen
Notably, I added a TODO value and a legend that prints at the end of the
script:
