Description
If I start the server with --skip-grant-tables, then CREATE EVENT doesn't work:
The error message is extremely misleading: "Cannot proceed, because event scheduler is disabled", even if (as in this case) I've explicitly set EVENT_SCHEDULER=ON.

ERROR 1577 (HY000) at line 1: Cannot proceed, because event scheduler is disabled

This misleading message is a consequence of the fix for MDEV-19262, which changed the previous error message, even though it was more accurate in this case:

Ideas:
- There should be ≥2 error messages that actually distinguish the distinct cases:
- Cannot proceed, because event scheduler is disabled (should only be used when EVENT_SCHEDULER=DISABLED, obviously)
- Cannot proceed, because grant tables are disabled ((this case)
- Anything else?
- Is there any reason the event scheduler can't/shouldn't work with grant tables disabled?
- The event scheduler docs say nothing about not working with --skip-grant-tables.
