This adds a new category of error where the compiler cannot preserve
memoization exactly how as it was originally authored. We're adding a
new category here because it's not an actionable error, and allows us to
more specifically control whether it's reportable or not.

Pull Request resolved: https://github.com/facebook/react-forget/pull/2824
Summary: Currently Forget bails on mutations to globals within any callback function. However, callbacks passed to useEffect should not bail and are not subject to the rules of react in the same way.
We allow this by instead of immediately raising errors when we see illegal writes, storing the error as part of the function. When the function is called, or passed to a position that could call it during rendering, we bail as before; but if it's passed to `useEffect`, we don't raise the errors.
I did a double take when I thought we didn't handle returning the
error when reading the code and when I edited the code, typescript told
me that there's no need to return as creating the error will throw.
This PR makes it clear from the name of the function that we will throw.
Sorry about the thrash in advance! This removes the top level `forget` directory
which adds unnecessary nesting to our repo
Hopefully everything still works
