mofeiZ 152bfe3769 [compiler][rfc] Hacky retry pipeline for fire (#32164)
Hacky retry pipeline for when transforming `fire(...)` calls encounters
validation, todo, or memoization invariant bailouts. Would love feedback
on how we implement this to be extensible to other compiler
non-memoization features (e.g. inlineJSX)

Some observations:
- Compiler "front-end" passes (e.g. lower, type, effect, and mutability
inferences) should be shared for all compiler features -- memo and
otherwise
- Many passes (anything dealing with reactive scope ranges, scope blocks
/ dependencies, and optimizations such as ReactiveIR #31974) can be left
out of the retry pipeline. This PR hackily skips memoization features by
removing reactive scope creation, but we probably should restructure the
pipeline to skip these entirely on a retry
- We should maintain a canonical set of "validation flags"

Note the newly added fixtures are prefixed with `bailout-...` when the
retry fire pipeline is used. These fixture outputs contain correctly
inserted `useFire` calls and no memoization.

babel-plugin-react-compiler

React Compiler is a compiler that optimizes React applications, ensuring that only the minimal parts of components and hooks will re-render when state changes. The compiler also validates that components and hooks follow the Rules of React.

This package contains the React Compiler Babel plugin use in projects that make use of Babel. You can find instructions for using this plugin here: https://react.dev/learn/react-compiler
