ENH: Teach CTest to handle git repositories

This creates cmCTestGIT to drive CTest Update handling on git-based work
trees.  Currently we always update to the head of the remote tracking
branch (git pull), so the nightly start time is ignored for Nightly
builds.  A later change will address this.  See issue #6994.
