ENH: Create internal 'ctest --launch' tool

This creates an undocumented 'ctest --launch' mode.  It launches a
specified command and optionally records a failure in an xml fragment.
We will optionally use this in CTest's Build stage to record per-rule
build failure information when using Makefile generators.
