It's neither. The package installs a kernel (not just sources for the
kernel), like gentoo-kernel-bin, but it does so by building it locally,
just like just about every other package that doesn't have a name ending
in "-bin". On the other hand, gentoo-kernel-bin downloads a precompiled
kernel and just installs it locally, not compiling anything. The
gentoo-sources package also doesn't compile anything, it just dumps some
source code on your system for you to compile outside of portage.
In short:
| Downloaded | Installed
------------------+--------------+-------------
gentoo-sources | source code | source code
gentoo-kernel | source code | built kernel
gentoo-kernel-bin | built kernel | built kernel
