meson.bbclass: Add meson.bbclass
Add a class for packages that uses the meson build system.
Meson uses a cross-file that contain needed tools and information about
the host and target system. Such a file will be created in {WORKDIR}.
Meson only allows installation directories to be specified as relative
to prefix, except for sysconfdir, which can be absolute.
This patch is based on a prototype patch by
Ross Burton <ross.burton@intel.com>.
