Draw list bullets/numbers with CSS text color, not palette color

When CSS has been used to customize the text color, render the bullet
with the same color. This is consistent with web browsers, and with
Qt Quick rendering.

In QTextDocumentLayoutPrivate::drawListItem(), the pen color is the
text color, so use it instead of brush color.

Add a baseline test for lancelot: the background and general text
are customized, then some list items are customized further, and
some of them have colored text spans. Repeat with different styles
of numbered and bullet lists and checklists.
