Experimental DirectWrite font database
Adds an opt-in experimental DirectWrite-based font database. This cannot be the 100% replacement for GDI unfortunately, since quite a few font formats used on Windows are still unsupported. But it would be good to have it as an opt-in experimental feature since it should make it easier to solve multiple font selection issues we have on Windows. In order to still share the DirectWrite-specific code between the old and new database, this introduces a common base class. Note that the feature depends on DirectWrite 3 support (Windows 10). Fixes: QTBUG-74917 Change-Id: Ida08ec7ef4fda9fc78622ca4297909a727390a64 Reviewed-by: Allan Sandfeld Jensen <allan.jensen@qt.io>
