Add "Advanced Analytics" functionality from legacy charts to Time-Series ECharts

Is your feature request related to a problem? Please describe. Creating a stacked bar chart with a period-over-period line chart overlaid on top is currently very difficult to do in Superset using the Mixed Time Series Chart, as it requires you to calculate period-over-period metrics as a series as part of your dataset, rather than allowing you to calculate it after-the-fact as part of chart-creation.

Describe the solution you’d like It would be great to add the Advanced Analytics tab functionality (e.g. Rolling Window, Time Comparison, and pandas) to the ECharts Time-Series Charts (both single and mixed) as this is incredibly useful functionality, especially to easily create a YOY chart on top of a stacked bar chart (a very common chart type in many tools like Chartio, Excel, etc.)

E.g. in Chartio:

Describe alternatives you’ve considered Currently, we use the existing legacy Line Chart’s “Advanced Analytics” functionality to build a separate YOY chart (1 year time shift + percentage change) that we express separately from our bar chart, but it’s not always as useful.

@junlincc Is it possible to reopen this issue until support has been added to the Mixed Time Series Chart as well?
