MDEV-33751 Assertion `thd' failed in int temp_file_size_cb_func(tmp_file_tracking*, int)

Browse Source 
Changes:
- Fixed that MyISAM and Aria parallel repair works with tmp file limit.
  This required to add current_thd to all parallel workers and add
  protection in my_malloc_size_cb_func() and temp_file_size_cb_func() to
  be able to handle shared THD's.  I removed the old code in MyISAM to
  set current_thd() as only worked when using with virtal indexed
  columns and I wanted to keep the Aria and MyISAM code identical.

Other things:
- Improved error messages from Aria parallel repair and
  create_internal_tmp_table_from_heap().
