Add filename, line, column to Error

[Sytten]

Hi! Transitioning from quickjs, I was to having the filename (JS_ATOM_fileName), line (JS_ATOM_lineNumber) and column (JS_ATOM_columnNumber) on the Error object. I think they were added in the build_backtrace method (https://github.com/bellard/quickjs/blob/6e2e68fd0896957f92eb6c242a2e048c1ef3cae0/quickjs.c#L6559).

It was useful when you want to offer to the user some indication of where the error comes from without displaying the whole stack trace.

I can't seem to find it now, but IIRC we removed those because they are nonstandard.

You can use Error.prepareStackTrace to add them to the error object if you need to.
