Fix application fonts with DirectWrite font engine

There is no way to add fonts to the system font collection with
DirectWrite. Instead you have to write custom collections. But
that would mean keeping two instances of the same font data in
memory since we are already registering them for the GDI engine,
and we have no way of knowing which engine will be used. When
we at some point replace the GDI engine completely, we could
implement this in the proper way, but for now, instead of looking
up the equivalent to the LOGFONT in DirectWrite's system font
collection, we look it up using GDI and then convert the HFONT
to DirectWrite.

[ChangeLog][Windows][Text] Fixed disabling hinting for application
fonts, e.g. when automatic scaling by device pixel ratio is in
effect.
