MDEV-34860 Implement MAX_EXECUTION_TIME hint

Browse Source 
It places a limit N (a timeout value in milliseconds) on how long
a statement is permitted to execute before the server terminates it.

Syntax:
SELECT /*+ MAX_EXECUTION_TIME(milliseconds) */ ...

Only top-level SELECT statements support the hint.
