Replace the local MAKE_TAG macro definition with QFont::Tag's support
conversions to and from big endian byte ordering.
Also replace the incorrect usage of the big-endian-producing MAKE_TAG
macro in the DirectWrite implementation. The IDWriteFontFace
documentation suggests to use the DWRITE_MAKE_OPENTYPE_TAG macro for
producting the tag, which is equivalent to the LittleEndian
implementation of QFont::Tag::value.
