[compiler] Improve error message for mutating hook args/return (#33513)
The previous error message was generic, because the old style function
signature didn't support a way to specify a reason alongside a freeze
effect. This meant we could only say why a value was frozen for
instructions, but not hooks which use function signatures. By defining a
new aliasing signature for custom hooks we can specify a reason and
provide a better error message.

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.

More information about the design and architecture of the compiler are covered in the Design Goals.

More information about developing the compiler itself is covered in the Development Guide.
