Superset 4.1.2: Disable Auto Time Filter for {{ from_dttm }} / {{ to_dttm }}

This patch disables Superset’s built-in time_range filter whenever Jinja templates {{ from_dttm }} or {{ to_dttm }} appear in any of the following:

• Dataset SQL
• Calculated metrics
• Adhoc filters

As a result, no automatic date filter is applied when those templates are used.
