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.
