widl [1/3]: Use the correct functions for interface pointers in stubs

[Dan Hipschman]

This patch fixes a problem with generating stubs when interface pointer
arguments are involved.  The correct functions to call are
NdrInterfacePointerFoo, but widl will output NdrPointerFoo.  I don't
have a "reasonable" test for this yet, but I've tested it with some
incredibly ugly code.  Once I get widl to generate a working oaidl_p.c
(this patch is part of that work), I think there's a reasonable test in
oleaut32/tests/tmarshal.c.

For what it's worth, when I drop widl's oaidl_p.c (minus IPropertyBag,
which is unimplemented and has call_as attributes), all the tests
under oleaut32/tests pass except tmarshal.c, which crashes pretty close
to the beginning.
