Note: This requires an update to the tst_qtextlayout test, because
the test assumed that the Arabic string would always yield a run
of two glyphs. This was a side effect of how Harfbuzz handled
Qt's test font, which has zero font tables and cannot be used for
shaping. With the Harfbuzz update, the Arabic text here yields a
single cluster instead, which actually makes more sense, so the
test has been made a bit more robust to support both cases.

Quite a big change since it has been several years since
the last update. This drops the Harfbuzz source on top
of the existing code in Qt, and does the following
additional changes:
1. Deletes old source files that have been removed upstream
(everything named foo-private.hh is now renamed to just
foo.hh for instance).
2. Added a header guard to config.h because it may be
double-included.
3. Implement a memory barrier needed by hb-atomic.hh.
4. Changed the signature of hb_atomic_int_impl_add()
to take a pointer to match new upstream.
5. Updated .pro file to include new files and removed
old.
6. Updated qt_attribution.json
7. No longer disable deprecated APIs since
hb_ot_tags_from_script() is now deprecated and is used
from Qt code.
8. Updated and applied the patch in patches/ for CoreText.
9. Updated tst_qtextscriptengine::thaiWithZWJ() according to
changes in Harfbuzz and disabled it for system-harfbuzz,
since this may be an older version of harfbuzz depending on
the system.
