Move gn secondary_source to the build/ directory

It's a goodness to sequester build configuration in the build/
directory. The gn secondary_source stuff was under tools/gn for
historical reasons, so move it to a more appropriate place.

BUG=None
TEST=do a gn build of base_unittests, run said unittests.
