[PATCH 1/2] msctf/tests: Add multi-threaded apartment test for ITfSource_AdviseSink

[Rémi Bernon]

We expect it to fail because the ITfUIElementSink interface is flagged
as "local" and cannot be marshalled, and because ITfThreadMgr is flagged
with "threading(apartment)" and cannot be instanciated in the MTA.

Note: The real purpose of the test is to reproduce an unwinding issue
that has nothing to do with msctf or ole, but that is triggered by this
specific code with WINEDEBUG=-all.
