dgcov: add support for *.gcda.gcov.json.gz files of gcov 9.1+

Details

    Description

      1. dgcov should be supported with gcc version gcc 4.9.4+ since there is -i option introduced.
      2. json format found from here that is introduced with 9.1.0. Looking from all release changes for 9.1.0

      The following improvements to the gcov command-line utility have been made.
      		 
       
      The gcov tool received a new option --use-hotness-colors (-q) that can provide perf-like coloring of hot functions.
      		 
      The gcov tool has changed its intermediate format to a new JSON format.

      and seems that in that version intermediate format was deprecated.
