tdf#99643 OLE automation bridge: fix 64-bit pointer conversions

Browse Source 
XBridgeSupplier2::createBridge() is always called in-process and should
therefore expect and create Anys with native-sized encoded pointers,
so use sal_uIntPtr.

Change-Id: Ia757ff38568b07de8085a1a9d323d806bcca0f63
Note: Currently all calls in LO code are with source=UNO, target=OLE.
