      Description

      Need support for query stats to provide statistics on the various TRIM operations performed for the page-compression/NVM Compression workload.

      For the 2K format block-size it shows none
      =======
      Innodb_page_compression_saved 364564353024
      Innodb_page_compression_trim_sect512 0
      Innodb_page_compression_trim_sect4096 0
      ========

      For the 512B and 4K format block-size it shows the following
      =======
      Innodb_page_compression_saved 284889649152
      Innodb_page_compression_trim_sect512 0
      Innodb_page_compression_trim_sect4096 13063475
