Support ordering of breakdown elements within waterfall

The default waterfall diagram orders the effects according to their value rather than by the sort of the breakdown elements.

In reporting it is sometimes required to have the same order of breakdowns in all categories.

The same request has come up multiple times over the last years, e.g.:

• Solved: Waterfall chart Breakdown custom sort - Microsoft Fabric Community
• Solved: Waterfall chart - change breakdown order - Microsoft Fabric Community
• Waterfall Chart - Sorting by Breakdown - Microsoft Fabric Community

Many custom waterfalls have been created because of this limitation. Please add this feature to the default chart!
