Migrate checked_agg_time_dimension to `checked_agg_time_dimension_f…

…or_measure`

DSI 0.1.0dev10 moved `checked_agg_time_dimension` from the `Measure`
protocol to the `SemanticModel` protocol as `checked_agg_time_dimension_for_measure`.
This finishes a change where for a given measure either the `Measure.agg_time_dimension`
or the measure's parent `SemanticModel.defaults.agg_time_dimension` needs to be
set, instead of always require the measure's `Measure.agg_time_dimension`.
