   Add AlterTableAddPartitionStatement and make ALTER TABLE ... ADD PARTITION 
go through the same catalog/table resolution framework of v2 commands.
   
   ### Why are the changes needed?
   <!--
   Please clarify why the changes are needed. For instance,
     1. If you propose a new API, clarify the use case for a new API.
     2. If you fix a bug, you can clarify why it is a bug.
   -->
   It's important to make all the commands have the same table resolution 
behavior, to avoid confusing end-users. e.g.
   ```
   USE my_catalog
   DESC t // success and describe the table t from my_catalog
   ALTER TABLE t ADD PARTITION (id=1) // report table not found as there is no 
table t in the session catalog
   ```
   
   ### Does this PR introduce any user-facing change?
   <!--
   If yes, please clarify the previous behavior and the change this PR proposes 
- provide the console output, description and/or an example to show the 
behavior difference if possible.
   If no, write 'No'.
   -->
   Yes. When running ALTER TABLE ... ADD PARTITION, Spark fails the command if 
the current catalog is set to a v2 catalog, or the table name specified a v2 
catalog.
   
   ### How was this patch tested?
   <!--
   If tests were added, say they were added here. Please make sure to add some 
test cases that check the changes thoroughly including negative and positive 
cases if possible.
   If it was tested in a way different from regular unit tests, please clarify 
how you tested step by step, ideally copy and paste-able, so that other 
reviewers can test and check, and descendants can verify in the future.
   If tests were not added, please describe why they were not added and/or why 
it was difficult to add.
