ENH: Refactor cmCTest test part representation

This introduces the name "part" to denote a portion of the testing and
submission process performed by ctest.  We generalize the boolean
indicating whether each part is enabled into a structure to which more
information can be added later.  We provide bi-directional mapping
between part id and part names.
