evas/cserve2: Use width and horizontal bearing from

 glyph metrics.
Instead of having to render the glyph to get the width and horizontal
bearing of it, it's possible to get this information from the glyph
metrics (which are available on the glyph slot).

This change now allows Evas to only render the glyph at the rendering
phase, instead of having to render it during layout phase.
