[compiler][playground] (1/N) Config override panel (#34303) 
## Summary
Part 1 of adding a "Config Override" panel to the React compiler
playground. The panel is placed to the left of the current input
section, and supports converting the comment pragmas in the input
section to a JavaScript-based config. Backwards sync has not been
implemented yet.

NOTE: I have added support for a new `OVERRIDE` type pragma to add
support for Map and Function types. (For now, the old pragma format is
still intact)

## Testing
Example of the config overrides synced to the source code:

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.
