This PR makes it so we always emit a const VariableDeclaration for
compiled functions in gating mode. If the original declaration's parent
was an ExportDefaultDeclaration we'll also append a new
ExportDefaultDeclaration pointing to the new identifier. This allows
code that adds optional properties to the function declaration to still
work in gating mode

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.
