commit ddaa36a20e8d517fb591f034fca5bc1b9a2d4d9d
Author: nikunjb <nikunjb@chromium.org>

Clean up sparse_histogram.h header by moving UMA_HSITOGRAM_SPARSE_SLOWLY to histogram_macros.h

Also modifying include in the repo which points to sparse_histogram.h to histogram_macros.h

All changes to file not in base/metrics is for using histogram_macros.h instead of sparse_histogram.h

We are doing this to consolidate header files and cleanup base/metrics externally usable histogram macros.
