Hard-code the shared InnoDB temporary tablespace ID

Details

    Description

      MySQL 5.7 supports only one shared temporary tablespace.
      MariaDB 10.2 does not support any other shared InnoDB tablespaces than the two predefined tablespaces: the persistent InnoDB system tablespace (default file name ibdata1) and the temporary tablespace (default file name ibtmp1).

      InnoDB is unnecessarily allocating a tablespace ID for the predefined temporary tablespace on every startup, and it is in several places testing whether a tablespace ID matches this dynamically generated ID.

      We should use a compile-time constant to reduce code size and to avoid unnecessary updates to the DICT_HDR page at every startup.

      Using a hard-coded tablespace ID will also make it easier to remove the TEMPORARY flag from FSP_SPACE_FLAGS in MDEV-11202.
