Fixes #31331 ## Summary There is a bug in playground(https://github.com/facebook/react/issues/31331) which doesnt support 'use memo' or 'use no memo' directives. Its misleading while debugging components in the playground ## How did you test this change? Ran test cases and added a few extra test cases as well ## Changes 1) Adds support for 'use memo' and 'use no memo' 2) Cleanup E2E test cases a bit 3) Adds test cases for use memo 4) Added documentation to run test cases ## Implementation `parseFunctions` returns a set of functions to be compiled. But, it doesnt filter out/handle memoized opted/un-opted functions using directives. ive just created a `compile` flag to enable/disable compiling [here](https://github.com/facebook/react/pull/31561/files#diff-305de47a3fe3ce778e22d5c5cf438419a59de8e7f785b45f659e7b41b1e30b03R113) Then I am just skipping those functions from getting compile [here](https://github.com/facebook/react/pull/31561/files#diff-305de47a3fe3ce778e22d5c5cf438419a59de8e7f785b45f659e7b41b1e30b03R253)
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.
