  [text-wrap-style:pretty] Refactor line width calculations.

Reviewed by Alan Baradlay.

This PR refactors out the logic for computing line width from sliding width and
updates text-wrap-style:pretty and text-wrap-style:balance to use correct widths
of the inline items when performing cost/raggedness calculations.

This will also remove duplicate code and functionality. This will also enable use to
backtrack line widths for text-wrap-style:pretty.

Finally, line width backtracking is necessary to enable hyphenation: these will be
landed in a follow up PR.
