[explore][adhoc filter] "use latest_partition" operator disappeared

[graceguo-supercat]

in #9637 we added an optional operator for adhoc filter: use latest_partition. It will show up when datasource has single partition. This feature was lost since recent filter redesign work. Note: this feature is not enabled by feature flag. The operator should show up based on the attribute of dataset.

Before

Current

How to reproduce the bug

1. Create a new chart from dataset which has single partition
2. Check adhoc filter operators
3. if you can choose use latest_partition, make sure it generate correct custom sql with latest_partition template.

Environment

latest master
