jamie dale c36736f346 Insert a substitute glyph for narrow nbsp and thin space if the font doesn't support them ...

This uses 2/3rd the width of a normal space, and also moves the handling of zwsp into a common point rather than duplicate it between the kerning a HarfBuzz shaping paths, as well as giving the composite font first refusal at handling all whitespace as it may have better metrics than our own approximation.
