MDEV-26938 Support descending indexes internally in InnoDB (server part)

Browse Source 
* preserve DESC index property in the parser
* store it in the frm (only for HA_KEY_ALG_BTREE)

* show it in SHOW CREATE
* skip DESC indexes in opt_range.cc and opt_sum.cc
* ORDER BY test

This includes a fix of MDEV-27432.
