Jonathan Clark 1afdda6bca tdf#164493 Update script change algorithm to always make progress ...

Fixes ofz#385256118 Timeout on ImpEditEngine::InitScriptTypes.

Previously, the script assignment algorithm could backtrack in certain
cases where a script run ends with weak characters that should be
included in the following run. Fuzz testing unearthed a case involving
right-to-left override and a CJK combining mark, which caused the
algorithm to make no progress and hang.

The algorithm now always makes progress on each iteration.
