refactor&feature:

(1) Uniform series data union logic; previous they are implemented in several inconsistent ways and error-prone. And also strict the extent calculation with uniformed utilities.
(2) Refactor Scale - uniform the implementation of the numeric transformations (such as axis breaks, logarithm, ordinal related handling) with a decorator pattern and decouple them from Scale class hierarchy. This brings consistent handling for details and enables further extension.
(3) Refactor Scale - decouple "axis nice" logic from Scale and make the "axis nice" and "axis align" implemented in the same code style. This removes override (hard to read and maintain), and uniforms the parameters of IntervalScale (previous its parameters can be generated by itself or outside, which is confusing), and reduce scale-type-specified handling (e.g., if (isLogScale) ...) in calculation.
(4) Enable "value" axis and "log" axis to render "bar" and "pictorialBar" series without overflowing the axis. Previously only "time" axis enables that on only "bar" series. Introduce "SCALE_EXTENT_KIND_MAPPING" to cover this generalized behavior and use strict "clip" for bar series without extra margin (a previous compromise). And clarify `barGrid` code accordingly, which removes duplicated time-consuming calculation in "bandWidth" calculation. Close #19972. Close #17858. Close #12720. Close #13321. Close #20718.
