[PATCH 0/2] MR10856: oleaut32: Don't include IDispatch slots in stored cbSizeVft for TKIND_DISPATCH.

[Francis De Brabandere (＠francisdb)]

ICreateTypeInfo2_fnLayOut starts cbSizeVft at 7*ptr_size for TKIND_DISPATCH
to position own funcs after the IDispatch vtbl, then increments per added
func. The own funcs receive correct oVft offsets that way, but the
resulting stored cbSizeVft is too large by exactly the IDispatch vtbl
size: GetTypeAttr later derives cFuncs as cbSizeVft/ptr_size and so
reports own_count + 7 instead of own_count. Subtract the prefix at the
end of LayOut so cFuncs matches native, both in-memory and after
SaveAllChanges + LoadTypeLibEx. Public cbSizeVft is unchanged: GetTypeAttr
already overrides it to sizeof(IDispatchVtbl).
