BED-5464 - Additional CySQL Fixes

[zinic]

Description

This changeset addresses a few tickets:

• BED-5464
• BP-1396
• And an additional test case missed for BP-1366

Motivation and Context

Refactors to better support more robust translations for complex user queries. Some of these ended up stressing some shortcuts and hacks in managing symbols that get projected between query steps.

How Has This Been Tested?

More test cases added for each ticket.

Types of changes

• Chore (a change that does not modify the application functionality)
