wina11y: Move and simplify casting for Get_ToATInterface

Move the casting from AccObjectManagerAgent::Get_ToATInterface to
AccObjectWinManager::Get_ToATInterface and just do a
`reinterpret_cast<HWND>(...)` right away instead of a
`static_cast<HWND>(reinterpret_cast<void*>(...))`.

This is in preparation of dropping the AccObjectManagerAgent
indirection altogether.
