    Original Commit Message:
    
        Refactor the CallApiCallback builtin to
    
        - pass the context as with other stubs, and
        - pass holder and call data in registers.
    
        This avoids having to place holder and call data onto the stack, and
        thus makes it possible to easily call the CallApiCallback builtin from
        other builtins while just forwarding the (stack) arguments. The idea
        is to use this in the future to optimize the general case of calling
        into any API method via a FunctionTemplateInfo and doing appropriate
        security and/or interface checks upfront as necessary (eventually making
        the HandleApiCall C++ builtin obsolete at some point).
