make SalLayoutGlyphsImpl::cloneCharRange() work for RTL runs too

Glyphs are in the reverse order in this case, so the character
positions for the wanted range must be treated that way. This improves
e.g. the second attachment from tdf#112989. Unfortunately it's
not that significant, as arabic glyphs are often unsafe to break at.
