Add support for polyphonic greek
Merge patch c0006e05f32ecd6f16825b799d2bce345c166433 from harfbuzz and add autotests to QTextScriptEngine. Support for polyphonic greek is implemented by mapping decomposed greek character sequences to their composed characters in the greek extended unicode range (U+1f00 - U+1fff). Task-number: QTBUG-391 Reviewed-By: Simon Hausmann
