Fix CallData setup for Script::run
By calling JSCall with an ExecutionContext as first parameter, the
compiler would implicitly create a temporary Scope object in order to be
able to do the call. However, the scope would then wipe the stack
when it is being destructed. So subsequently retrieving argc would
always result in 0 arguments.
To prevent accidents like this, all Scope constructors are now explicit,
and the QV4::Script's ExecutionContext is renamed from scope to context.
