Fix trailing spaces problem by not adding it to QScriptLine.length

It seems to be the only sane way to fix it. Previous attempts to
fix it by compensating the trailing space width all failed in some
cases, one of the trickiest is when we are having embedded LTR text
that has trailing spaces in a RTL paragraph.

In this patch we leave line.length not including the trailing space
length, but saving it to a separated variable, so that we can always
add it back when needed (QTextLine::textLength() for instance).

It fixed all the problems in different alignments of both RTL and
LTR text. And no regression is found yet.
