[lint] Enable custom hooks configuration for useEffectEvent calling rules (#34497)
We need to be able to specify additional effect hooks for the
RulesOfHooks lint rule
in order to allow useEffectEvent to be called by custom effects.
ExhaustiveDeps
does this with a regex suppplied to the rule, but that regex is not
accessible from
other rules.
This diff introduces a `react-hooks` entry you can put in the eslint
settings that
allows you to specify custom effect hooks and share them across all
rules.
This works like:
```
{
settings: {
'react-hooks': {
additionalEffectHooks: string,
},
},
}
```
The next diff allows useEffect to read from the same configuration.
