Use multithreaded instead of apartment-threaded

Uses the multithreaded COM threading model in pdfium_test, instead of
the apartment-threaded one. Correct usage of the apartment-threaded
model requires a message pump, which console applications don't have.

The XPS object model service supports both threading models equally, so
the models are the same for us otherwise.
