Move Windows font DB and engines to QtFontDatabaseSupport
This allows creating or extending QPA plugins to provide access to QFont and related types. It concerns both GDI and DirectWrite engines, as well as the regular and the freetype based font databases. The qt.qpa.fonts logging category has been moved together into the QWindowsFontDatabase related files to avoid depending on the qwindowscontext.h header file. Finally, QwindowsNativeImage is following pending a future refactor with similar code in qpixmap_win.cpp and the Windows XP style.
