- This commit rely on MDEV-28391
- When temporary table shadows the base table, error is raised (it can be changed if needed),
since the procedure is relying on creating the views and view cannot be created from the temporary table.

- When arguments to the procedure contain quote in the name, procedure fails with parsing error.
The reason was because additional quoting is done when testing TEMPORARY table with the same name.

- The problem:
==============
- Commit f7216fa63d created the check function for
default temporary storage engine and in case the SE doesn't support temporary tables
the error `ER_ILLEGAL_HA_CREATE_OPTION` is raised.
Before that commit in such cases temporary tables were created by silently substituting
default SE (RocksDB, Connect, PerfSchema) with MyISAM.
- The test `pr_diagnostics.test` was modified in that commit with raising the error,
since I didn't check the root cause of test itself.
- The solution:
===============
- This commit update the root case: procedure `ps_setup_save()` that uses temporary
tables created from performance schema tables definition using `LIKE`, what is not supported.
The suggested fix is to use InnoDB table by using `AS SELECT`.
- Note that test `pr_diagnostics` will raise this error for `medium/full` third argument,
but not for `current` value of third argument.
- Additionally this patch updates the test case of commit f7216fa, by adding missing relation
between temporary tables and Performance schema in `perfschema.misc` test.

- Innodb is not always available, which means t is not always
possible to use innodb system variables, or innodb information schema
tables.
Thus creation of objects that use Innodb information_schema is enclosed
into BEGIN NOT ATOMIC blocks with dummy SQLEXCEPTION handler.
- sys_config table uses Aria, just like other system tables.
- several tables that exist in MySQL, do not exist in MariaDB
performance_schema.replication_applier_status, mysql.slave_master_info,
mysql.slave_relay_log_info
