innodb_flush_neighbors is not being ignored for system tablespace on SSD

Details

    Description

      It turns out that fil_system.sys_space->rotational() will wrongly hold at least on 10.5 where I tested it. Maybe we only ever invoke fil_node_t::find_metadata() on .ibd files, but never on the special tablespaces (system tablespace, temporary tablespace, undo tablespaces).

      Note: /dev/shm will be reported to be rotational.
      Note2: it was fixed in 10.5.7 by MDEV-23855, but 10.4 still has it.
