app-text/poppler-data: add additional cMaps files needed by ghostscript

Quoting John from the Bug;
>Ghostscript's official binary is built with bundled CMaps; on Gentoo, these are unbundled
>in favor of those provided by app-text/poppler-data. Ghostscript's CMaps include 3 files
>missing from poppler-data: Identity-H, Identity-V, and Identity-UTF16-H (CMap
>resources for the special-purpose Adobe Identity-0 ROS), and the lack of these files is causing this issue.
>
>Fedora and Arch avoid this problem by using GS-bundled CMaps, while Debian
>(and older versions of Fedora) relies on CMaps from poppler-data (like Gentoo does)
>and includes the missing files in their poppler-data package, installing them to
>/usr/share/poppler/cMap. (According to Debian, upstream poppler-data refuses to include them.)
>
>Two of these files are provided by Adobe Type Tools:
>https://github.com/adobe-type-tools/cmap-resources/tree/master/Adobe-Identity-0/CMap
>
>and the third is from Artifex themselves:
>http://git.ghostscript.com/?p=ghostpdl.git;a=blob;f=Resource/CMap/Identity-UTF16-H;hb=HEAD
>
>You can copy these 3 files to /usr/share/poppler/cMaps for a quick-and-dirty verification that
>they resolve the issue; by doing so, I was able to produce a match for gs-fail-good.jpg and
>pass the WeasyPrint test suite using ghostscript-gpl-9.56.1 (and 10.0). Including
>these files with poppler-data seems like the best approach. (As noted in
>Ghostscript's LICENSE file, Identity-UTF16-H is licensed under AGPL-3+.)
