### What changes were proposed in this pull request?
Now that `AnalysisOnlyCommand` in introduced in #32032, `CacheTable` and `UncacheTable` can extend `AnalysisOnlyCommand` to simplify the code base. For example, the logic to handle these commands such that the tables are only analyzed is scattered across different places.
### Why are the changes needed?
To simplify the code base to handle these two commands.
### Does this PR introduce _any_ user-facing change?
No, just internal refactoring.
### How was this patch tested?
The existing tests (e.g., `CachedTableSuite`) cover the changes in this PR. For example, if I make `CacheTable`/`UncacheTable` extend `LeafCommand`, there are few failures in `CachedTableSuite`.
Closes#32220 from imback82/cache_cmd_analysis_only.
