[packages/tools] Consolidate tools into tools bundle

This consolidates the package definition files for many command line
tools in the garnet directory to the //garnet/packages/tools directory
and includes them in //bundles/tools so it's easier to build them as
unit.

This leaves a few forwarding declarations behind for packages
referenced from topaz.git.
