This PR updates the eslint plugin to report unused opt out directives.
One of the downsides of the opt out directive is that it opts the
component/hook out of compilation forever, even if the underlying issue
was fixed in product code or fixed in the compiler.

Summary:
The change earlier in this stack makes it less safe to have ref enforcement disabled. This diff enables it by default.

Updates the prettier config to format all `.ts` and `.tsx` files in the
repo using the existing defaults and removing overrides.
The first commit in this PR contains the config changes, the second is
just the result of running `yarn prettier-all`.
---
* panicThreshold: `all_errors` -> `none`
* inject an error logger through compiler config (instead of using exceptions)
We currently report at most one lint warning per file, this lets us exhaustively report all available ones (see new
test fixture for example)

Previously we would attempt to parse code in the eslint plugin with the
HermesParser first as it can handle some TS syntax. However, this was
leading to a mis-parse of React hook calls with type params (eg,
`useRef<null>()` as a BinaryExpression rather than a CallExpression with
a type param. This triggered our validation that Hooks should not be
used as normal values.
To fix this, we now try to parse with the babel parser (with TS support)
for filenames that end with ts/tsx, and fallback to HermesParser for
regular JS files.

The eslint rule seems to false positive on this typescript syntax, but
strangely the compiler does not

During the demo I might show an example of fixing a
CannotPreserveMemoization error. But I don't want to make that
reportable by default, so this PR allows configuration like so
```js
module.exports = {
root: true,
plugins: [
'eslint-plugin-react-compiler',
],
rules: {
'react-compiler/react-compiler': [
'error', {
reportableLevels: new Set([
'InvalidJs',
'InvalidReact',
'CannotPreserveMemoization'
])
}
]
}
}
```

First attempt at making the linter work with advanced TypeScript syntax
Falls back to the babel parser for some advanced syntax like string template
syntax.
This is pretty hacky as it doesn't take in any parsing options that are
configured for the outer ESLint parser, not sure how that could be handled.
