lauren f99241b2e6 [compiler] Add enableUseKeyedState flag and improve setState-in-render errors (#35230 )

Adds a new `enableUseKeyedState` compiler flag that changes the error
message for unconditional setState calls during render.

When `enableUseKeyedState` is enabled, the error recommends using
`useKeyedState(initialState, key)` to reset state when dependencies
change. When disabled (the default), it links to the React docs for the
manual pattern of storing previous values in state.

Both error messages now include helpful bullet points explaining the two
main alternatives:
1. Use useKeyedState (or manual pattern) to reset state when other
state/props change
2. Compute derived data directly during render without using state

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
