LibWeb: Do not create a RootVector to invoke IDL callbacks

Browse source 
These callbacks are evaluated synchronously via JS::Call. We do not need
to construct an expensive RootVector container just to immediately
invoke the callbacks.

Stylistically, this also helps indicate where the actual arguments start
at the call sites, by wrapping the arguments in braces.
