- The problem:
==============
- Commit f7216fa6 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 f7216fa6, by adding missing relation
  between temporary tables and Performance schema in `perfschema.misc` test.
