Removes dmalloc support (#2239) (#2587)

This has not been used to debug the library in a very long time. Most
developers use valgrind, -fsanitize=address, or some other memory checker
instead of this library.

This removes:
    * dmalloc.h include from H5private.h
    * --with-dmalloc= Autotools configure option
    * HDF5_ENABLE_USING_DMALLOC CMake option
