General cleanup of module loading code, tried to reduce indentation in various methods on "JsRuntime" to improve readability. Added "JsRuntime::handle_scope" helper function, which returns a "v8::HandleScope". This was done to reduce a code pattern that happens all over the "deno_core". Additionally if event loop hangs during loading of dynamic modules a list of currently pending dynamic imports is printed.
