Branch/tag all projects with a single commit in release-tagging script.

This change updates the release script to use svnmucc to create all
the branches with one commit.

This will ensure that the git tag won't bounce around if the git
migration runs in-between separate commits creating a branch.

Additionally, update the list of projects to include all of the
projects in the monorepo, plus test-suite.
