JDK-8201539 Fix DirectWrite crash on Monocle.

COM was being initialized in two different places, WinApplication
and in directwrite.cpp when an IWICImagingFactory instance is created
for the first time (on the same d2d thread). The second initialization
has no further effect. But then CoUninitialize is called, which
uninitializes COM and makes IWICImagingFactory go stale.
