[PATCH 0/4] MR10857: Draft: oleaut32: Bound GetFuncDesc impltypes walk by stored cbSizeVft.

[Francis De Brabandere (＠francisdb)]

ITypeInfoImpl_GetInternalDispatchFuncDesc walked impltypes whenever any
impl type was registered, surfacing inherited IDispatch slots ahead of
own funcs in the index space. That matches MIDL-built TKIND_DISPATCH
typelibs (where cbSizeVft includes inherited slots and cFuncs is
inflated to match) but mismatches ICreateTypeLib2-built ones where
cbSizeVft only spans own funcs and GetFuncDesc should expose only those.
Skip the walk when the stored cbSizeVft has no room beyond own_count *
ptr_size, so GetFuncDesc on ICreateTypeLib2 typelibs hits own funcs at
indices 0..cFuncs-1 and returns TYPE_E_ELEMENTNOTFOUND past the end,
matching native.

This is needs !10856 merged first
