post-merge: --ps-protocol fixes

Browse Source 
Includes:

MDEV-17302 Add support for ALTER USER command in prepared statement

and

MDEV-17673 main.cte_recursive fails in bb-10.4-ps branch in --ps

  Set correct SELECT_LEX linkage for recursive CTEs.
  Do not delegate this job to TABLE_LIST::set_as_with_table,
  because it is only run on prepare, while With_element::move_anchors_ahead
  is run both on prepare and execute (fix by Igor)
