mofeiZ 2c2fd9d12c [compiler][playground] parse compiler configs using json5 (#36159)
Compiler config parsing is currently done with new Function(...) which
is a XSS vulnerability. Replacing this with json parsing for safety
reasons.

Almost all compiler options (except for moduleTypeProvider) are json
compatible, so this isn't a big change to capabilities. Previously
created playground URLs with non-default configs may not be compatible
with this change, but we should be able to get the correct config
manually (by reading the JS version)

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.
