LibJS: Lazily collect stack trace information

Browse source 
The previous implementation was calling `backtrace()` for every
function call, which is quite slow.

Instead, this implementation provides VM::stack_trace() which unwinds
the native stack, maps it through NativeExecutable::get_source_range
and combines it with source ranges from interpreted call frames.
