Summary [LFC][IFC] Construct dedicated runs when the inline element requires it.

When a run overlaps multiple inline elements like this: <span>normal text content</span><span style="position: relative; left: 10px;">but this one needs dedicated run</span><span>end of text</span> The above content generates one long run <normal text contentbut this one needs dedicated runend of text> However the middle run needs to be moved independently from the rest of the content, hence it needs a dedicated inline run.

This is not supposed to be too common, but could improve if it ends up being in a hot codepath.

The positioning part is not done yet. This patch was actually in preparation for that (have to split the runs in order to move them independently)
