Add graphene to the book

[Douglas R. Reno]

As Xi noted in Ticket #13242, Graphene is going to be required for Mutter. Graphene is a thin layer around 3D and 2D graphics types to attempt to remove complexity and make development easier. A good explanation of how this package works can be found at ​https://github.com/ebassi/graphene/blob/master/README.md, however it basically provides types and rudimentary APIs for graphics objects.

This package should be a "M/N/NI" (meson, ninja, ninja install), and does not appear to require any special options.

I'll add this to "X Libraries"

Also, it appears that gst-plugins-base can use it:

renodr [ ~/Documents/blfs/BLFS/trunk/BOOK ]$ cat /usr/src/logs/gst-plugins-base-1.16.2.log | grep graphene
Run-time dependency graphene-1.0 found: NO (tried pkgconfig and cmake)
