Adam Harald Jørgensen 258af88b29 LibGUI: Fix search highlighting so that it matches the search query ...

There is a bug in the "search by typing" feature of
AbstractView, where the highlighted text shown in items' title won't
match the search query if the search query contains whitespace.
This commit fixes that bug.

The bug is caused by a bad assumption made in
AbstractView::draw_item_text about the Painter::draw_text API.
Specifically that the function passed to it will be called for each
code point of the string instead of for each drawable glyph.

This is fixed by not relying on looking at the length of the highlight
string, but instead looking at its content.
