MDEV-27159 Re-design the upper level of handling DML commandsbb-10.7-mdev-27159

This is the second commit for the task. This patch allows to execute only
single-table and multi-table DELETE statements using the method
Sql_cmd_dml::execute(). The code that handles INSERT statements has not
been touched.

This patch still does not have the final changes to handle UPDATE/DELETE
statements.
All tests from the main suite passed. With --ps-protocol one test from
opt_trace_security returns not the same result. This will be fixed soon.
