QFontEngine: Add handle() function
Both QFont::handle() and QFont::freetypeFace() used to
be available in Qt 4 but were removed in Qt 5. There's
currently no API to get access to the native font handle,
which the font engine holds in a way or another.
Similar to the way it was in Qt 4, the actual handle type
depends on the font engine currently in use. The types map
as follows:
Font Engine Native Handle
------------------------------------
DirectWrite IDWriteFontFace *
Freetype FT_Face
Mac CTFontRef
Win HFONT
All other font engines return a null handle.
