QFontComboBox: optimize handling of icons for delegate

Instead of move-assigning a new QIcon to the default-
constructed members, initialize them directly in the
ctor-init-list. Do this for the other data member, too,
for consistency.

Also use QStringLiteral instead of QLatin1String as
the argument to the QIcon ctor. This is correct, since
the string will never be modified, and saves two memory
allocations.
