MDEV-16708: Unsupported commands for prepared statements

Write a log event to the general log before executing a statemment in PS mode
This change fixes failure of the test main.log_tables when it is run in PS mode

Updated the test main.events_logs_tests to query mysql.general_log
for the command_type 'Query' and 'Execute' in order to have consistent
test result both in case the test is run with --ps-protocol and without it
