This inits a bunch of gnatcoll-* packages which are managed in the
gnatcoll-bindings repository. I have chosen not to include "bindings"
in their derivation or attribute names, since the GPR project
definitions themselves all don't contain that as well, instead they
are name `gnatcoll_${component}.gpr`.
