chore: restore SYSTEM RELOAD MODEL(S) and moniting view SYSTEM.MODELS
- This commit restores statements "SYSTEM RELOAD MODEL(S)" which provide
  a mechanism to update a model explicitly. It also saves potentially
  unnecessary reloads of a model from disk after it's initial load.

  To keep the complexity low, the semantics of "SYSTEM RELOAD MODEL(S)
  was changed from eager to lazy. This means that both statements
  previously immedately reloaded the specified/all models, whereas now
  the statements only trigger an unload and the first call to
  catboostEvaluate() does the actual load.

- Monitoring view SYSTEM.MODELS is also restored but with some obsolete
  fields removed. The view was not documented in the past and for now it
  remains undocumented. The commit is thus not considered a breach of
  ClickHouse's public interface.
