[ANALYZER-2548] - Sunburst slice proportions are not equivalent to the represented values' proportions

Three commits:
1. Rename of the AngleAxis to NormalizedAxis, to be able to use it for the size axes of Sunburst and Treemap.
2. Refactoring/clarification of the use of the option "UseAbs" in existing axes.
3. Actual fixes for Sunburst and Treemap.

@pamval please review.
