The revert looks good. To be clear @samvantran, this has not yet been released as a Spark update and as such does not affect any users?

### What changes were proposed in this pull request?
To support formatted explain for AQE.
### Why are the changes needed?
AQE does not support formatted explain yet. It's good to support it for better user experience, debugging, etc.

### Does this PR introduce any user-facing change?
No, this should be new feature along with AQE in Spark 3.0.
### How was this patch tested?
Added a query file: `explain-aqe.sql` and a unit test.
Closes apache#28271 from Ngone51/support_formatted_explain_for_aqe.
