Marko Mäkelä 49e2c8f0a6 MDEV-25743: Unnecessary copying of table names in InnoDB dictionary
Many InnoDB data dictionary cache operations require that the
table name be copied so that it will be NUL terminated.
(For example, SYS_TABLES.NAME is not guaranteed to be NUL-terminated.)

dict_table_t::is_garbage_name(): Check if a name belongs to
the background drop table queue.

dict_check_if_system_table_exists(): Remove.

dict_sys_t::load_sys_tables(): Load the non-hard-coded system tables
SYS_FOREIGN, SYS_FOREIGN_COLS, SYS_VIRTUAL on startup.

dict_sys_t::create_or_check_sys_tables(): Replaces
dict_create_or_check_foreign_constraint_tables() and
dict_create_or_check_sys_virtual().

dict_sys_t::load_table(): Replaces dict_table_get_low()
and dict_load_table().

dict_sys_t::find_table(): Renamed from get_table().

dict_sys_t::sys_tables_exist(): Check whether all the non-hard-coded
tables SYS_FOREIGN, SYS_FOREIGN_COLS, SYS_VIRTUAL exist.

trx_t::has_stats_table_lock(): Moved to dict0stats.cc.

Some error messages will now report table names in the internal
databasename/tablename format, instead of `databasename`.`tablename`.
