Structured stack trace access

[nitsky]

Hi, I would like to be able to access an exception's stack trace as structured data, so that I can apply source maps and serialize it to my own representation. Right now, QuickJS only exposes the stack trace as a string. With V8, I can do this with Error.prepareStackTrace. See here: https://v8.dev/docs/stack-trace-api. Thank you!

FWIW I implemented that like so: quickjs-ng/quickjs@555d837

I am going to merge @saghul code into quickjs, but I need some time to commit some other stuff before.
