embeddedobj: handle getting the visible area on a thread

The Windows OLE2 implementation of the embedded object interface assumes
that the same thread is used for loading and saving the embedded
objects.

This means that in case the main thread is used for loading (e.g. from
remote UNO, but with OnMainThead=true), but a
thread is used for storing (without an explicit OnMainThead=true), then
the underlying win32 API call failed and we returned a fixed size in
EmbeddedObjectRef::GetSize().

Fix the problem by explicitly checking for RPC_E_WRONG_THREAD and adding
error handling for that case.
