[0.4.10][USP10] Slightly tweak our intermediate fix

Browse source 
CORE-14226 was already effectively fixed by
0.4.11-RC-3-g 2fc4683
0.4.10-RC-3-g 71ea3f9
0.4.9-RC-4-g c19ce95
0.4.8-RC-5-g 937c261
and therefore no release ever was affected by it,
but today I undo the intermediate and sync to the final state of this fix
like we did commit it into master after Wine review
by master commit 0.4.12-dev-151-g c086edf366
The final fixes commit message:

[USP10] Don't mix character and glyph index caches. CORE-14226

Import Wine commits by Nikolay Sivov:
* d1e618d31da usp10: Use glyph index consistently in ScriptGetGlyphABCWidth().
* 8d018d8d1da usp10: Make sure metrics cache is used with glyph indices only.
* eda3a3e37da usp10: Remove extra parentheses.

Fixes font display in UltraISO and GOG and many other installers.
