LibJS: Convert Interpreter::run() to ThrowCompletionOr<Value>

Browse source 
Instead of making it a void function, checking for an exception, and
then receiving the relevant result via VM::last_value(), we can
consolidate all of this by using completions.

This allows us to remove more uses of VM::exception(), and all uses of
VM::last_value().
