Update Qt internals to use QChar::Script

...and remove the outdated QUnicodeTables::Script enum.
QFontEngineData now has one extra slot that never used
(engines[QChar::Script_Inherited]). engines[QChar::Script_Unknown],
if accessed, would be set with a Box engine instance, and could be used
as a minor optimization some time later.

In order to preserve the existing behavior, we map all scripts up to Latin to Common.
