commit ecc7961140968b3a9d464b65786bb3a3ca92bb42

Author: Monty <monty@mariadb.org>

    MDEV-34571 Add page accessed and pages read from disk to table_stats

    Trivial batch, using the handler statistics already collected for

    the slow query log.

    The reason for the changes in test cases was mainly to change to use

    select TABLE_SCHEMA ... from information_schema.table_statistics instead

    of 'show table_statistics' to avoid future changes to test results

    if we add more columns to table_statistics.
