Remove support for LyXRC::force_paint_single_char

Browse Source 
This workaround is not necessary anymore, and it complicates the code.

The variable itself will be removed after the landing of the branch on
master.

workaround that is not necessary anymore.
* Implement proper string metrics computation (with cache). Remove
useless workarounds which disable kerning and ligatures.
* when lyxrc.force_paint_single_char is false, draw also RtL text

removal, since we now rely on Qt to do things we use to do by
ourselves (see isArabic* and isHebrew* code in Encodings.cpp).

* Fix bugs uncovered by testing.
* Get rid of LyXRC::force_paint_single_char, which is only a workaround.
* Get rid of LyXRC::force_paint_single_char, which is not used anymore
in the source.
* Maybe get rid of LyXRC::rtl_support, which does not have a real use case.
