test(theme): fix test cases of v6
feat(matrix & calendar): (1). Support matrix col/row size option. (2). Support corner content options in matrix. (3) Support body content options. (4). Support matrix `mergeCells`. (5). Fix and refactor the matrix style options, conserning their inheritance and z-order and flexibility. (6). Support declaratively layout other components (including grid/polar/geo/graph coord sys, and dataZoom/visualMap/legend/... components) based on `matrix`/`calendar`. And and enhance the echarts API `convertToLayout`/`convertToPixel`, custom series API `api.coord`/`api.coord` to support this feature comprehansively. Considering the previous "pie layout on coord sys", introduce the `boxCooridnateSystem` and `createBoxLayoutReference` to all of the components and echarts for the overall coord sys infrastructure. (7). Add some test cases to matrix and calendar.
(1) [var => let/const] part I: Use eslint rule to check the diff between var and let: "no-use-before-define": "off" "@typescript-eslint/no-use-before-define": 2 no-redeclare: 2 block-scoped-var: 2 no-loop-func: 2 (2) By the way add some eslint rule and unify some code style.
