[EE] Organize the shared context and examples

What does this MR do?

This follows the documented convention. I only touched the CE files in this MR. I'll do a separate MR for the EE files.

This is the equivalent of !23323 (merged) but for ee/spec.

Does this MR meet the acceptance criteria?

Conformity

• Code review guidelines
• Merge request performance guidelines
