Add JSON_NORMALIZE function to normalize JSON values

Details

    Description

      Background is this question on stackexchange:

      https://dba.stackexchange.com/questions/208481/mariadb-compare-json

      The task is to provide a function that can be used to compare 2 json documents for equality, then name can be e.g JSON_NORMALIZE

      JSON_COMPACT already takes care of removing spaces, but this is not sufficient.
      Keys need to be (recursively) sorted , and if spaces are removed, then documents can be compared as binary strings.

            Note that Pandas doesn't do what this MDEV describes, but I think that it can give you some ideas about potential challenges when working with JSON.
