stdole2: Avoid defining Automation typedefs as part of the public library.
This fixes a regression introduced by
70e5d5fd2e8501f36e4f3b2bccbdc55e25d31ee4.
If the VARIANT struct is defined inside the library block, widl generates
typeinfo for it at index 0. This confuses typelibs that import stdole2.tlb.
