[PR] fix: gate element_at input types [datafusion-comet]
manuzhang opened a new pull request, #4702:
URL: https://github.com/apache/datafusion-comet/pull/4702
## Which issue does this PR close?
Part of apache/datafusion-comet#4505.
This PR does not address apache/datafusion-comet#4680 because that follow-up is assigned separately.
## Rationale for this change
`element_at` supports array and map inputs in Spark, but Comet only implements the array path. Reporting the map-input fallback through `getSupportLevel` keeps unsupported map inputs documented and handled consistently.
## What changes are included in this PR?
- Moves the `MapType` input fallback for `ElementAt` into `getSupportLevel`.
- Reuses the unsupported map-input reason in generated support documentation.
- Adds SQL fallback coverage for `element_at` on map inputs.
## How are these changes tested?
- Adds SQL tests
