Work in progress, i'm experimenting with revamping our diagnostic infra.
Starting with a better format for representing errors, with an ability
to point ot multiple locations, along with better printing of errors. Of
course, Babel still controls the printing in the majority case so this
still needs more work.

This rule currently has a few false positives, so let's disable it for
now (just in the eslint rule, it's still enabled in the compiler) while
we iterate on it.
Traverse program after running compiler transform to find untransformed
references to compiler features (e.g. `inferEffectDeps`, `fire`).
Hard error to fail the babel pipeline when the compiler fails to
transform these features to give predictable runtime semantics.
Untransformed calls to functions like `fire` will throw at runtime
anyways, so let's fail the build to catch these earlier.
Note that with this fails the build *regardless of panicThreshold*
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)

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'
])
}
]
}
}
```
