Bug 71287 - size specific design selection support in OS/2 table version 5

This feature requires the FreeType 2.5.1 or later at the build time.

Besides <range> element allows <double> elements with this changes.

This may breaks the cache but not bumping in this change sets at this moment.
please be aware if you want to try it and run fc-cache before/after to
avoid the weird thing against it.
