widl: Fix the writing typedefs to dispinterfaces and pointers to interfaces.

[Rob Shearman]

Currently, stdole2.tlb isn't generated correctly and causes "<failed>"
to appear instead of "FontEvents" in the IFontEventsDisp typedef when
viewed with oleview.

The problem is that the typedef should just generate a VT_USERDEFINED
record, but ends up generating a VT_PTR -> VT_USERDEFINED. So remove
the extra writing of VT_PTR entries.

Fix the skipped pointers checks in encode_type and encode_type to
specifically detect VT_UNKNOWN and VT_DISPATCH types which don't need
one level of pointers, whereas interfaces encoded as VT_USERDEFINED
do.
