Remove unused cmData and cmMakefile::DataMap

These were implementation details of the unused methods

  cmMakefile::RegisterData
  cmMakefile::LookupData

We simply remove the methods, members, and class cmData.

- * \brief Hold extra data on a cmMakefile instance for a command.
- *
- * When CMake commands need to store extra information in a cmMakefile
- * instance, but the information is not needed by the makefile generators,
- * it can be held in a subclass of cmData.  The cmMakefile class has a map
- * from std::string to cmData*.  On its destruction, it destroys all the
- * extra data through the virtual destructor of cmData.
