LibJS: Add file & line number to bytecode VM stack traces :^)
This works by adding source start/end offset to every bytecode instruction. In the future we can make this more efficient by keeping a map of bytecode ranges to source ranges in the Executable instead, but let's just get traces working first. Co-Authored-By: Andrew Kaster <akaster@serenityos.org>
