fix(sqla): support for date adhoc filter

[villebro]

SUMMARY

When sending a temporal Native Value Filter to a chart with a DATE column, the query errors out. This is due all temporal filters being encoded as datetime.datetime objects, irrespective of the target column being DATE, DATETIME or TIMESTAMP (we handle formatting of the temporal value in BaseEngineSpec.convert_dttm). This error is due to the SqlAlchemy Date and Datetime column types not being able to handle datetime and date objects respectively.

This PR replaces the SqlAlchemy Date type with DateTime, making it compatible with the logic in sqla/models.py.

BEFORE

TESTING INSTRUCTIONS

1. create a chart from a datasource that has a temporal column with DATE type
2. Add it to a dashboard and create a Value Filter referencing the DATE column
3. Emit a filter
4. See error
