[Lens] Offer option to extend auto-extend histogram and date histogram operations

[flash1293]

Currently some charts behave sub-optimal because the data table passed to the chart does not contain empty rows with a null value for some empty buckets (no documents). As this is a good use case in some cases, in most cases it causes confusing behavior (like #100301)

To unify the existing behavior without breaking backwards compatibility as far as feasible, the following steps have to be completed:

• Finish implementation for auto-extending number histogram by queried min and max values: Add new autoExtendBounds setting to histogram agg config #118855
• In Lens histogram, add an advanced setting switch "Include empty table rows" (with a tooltip to explain a bit). This is set to false for existing histograms (via migration) but set to true for newly created histograms. If set to true, it sets min_doc_count to false and enables the auto extend option from above
• In Lens date histogram, we always included empty rows, but didn't expand to the data range so far. Here, add advanced setting switch "Include empty table rows" (with a tooltip to explain a bit). This is set to true for existing date histograms (via migration) as well as newly created date histograms but can be turned off. It controls the min_doc_count setting and also extends the range to the currently selected time range. This last part is not backwards compatible - we are taking away the current setting of keeping empty buckets, but only in between buckets with data. I think this is fine because there's no good use case for this intermediate step.
