[GitHub] [superset] zhaoyongjie opened a new pull request, #21713: feat: support None operand with equal operator

zhaoyongjie opened a new pull request, #21713:
URL: https://github.com/apache/superset/pull/21713

   ### SUMMARY
   This PR intends to support the `None` operand with `Equal` and `Not-Equal` operators in Filters in QueryObject. Currently, the `In` operator had supported `None` operand calculation, in order to align that the `Equal` and` Not-Equal` should support as well.
    
   ```Python
   >>> result = mock_dataset.query({
       "metrics": ["count"],
       "filter": [{"col": "col", "val": None, "op": "=="}],
       "is_timeseries": False,
   })
   >>> result.query
   SELECT count(*) AS count
   FROM mock_dataset
   WHERE col IS NULL
   ```

Review Comment:
   bycatch: use `only_postgresql` decorator narrowing test case, and use `login_as_admin` to define the Flask app context, there's no logical change.

   @zhaoyongjie did you address the frontend issues that @villebro mentioned in a separate PR? If so could you reference this PR in said PR so there's a edge connecting the two PRs?
