(1) support name on <g>.
(2) some refactor.

(1) Support component focus blur.
The option `emphasis.focus` can be specified to enable this feature. `emphasis.focus` only supports the value `'self'`.
The option `emphasis.focusScope` is not supported in component. That is, the focus scope can be only a single component itself. All of the elements in this component will be blurred.
Added `Component['focusBlurEnabled']` to enable component blur.
(2) Support component hover link when highlight with a given name.
There probably be multiple elements share one region name while those region elements has no common ancestor. hover link enables them to be highlighted together.
Implementation: if a component implements `Component['findHighDownDispatchers']`,  dispatcher elements by a given name will be found and this feature is enabled.
(3) Support component highlight/downplay be triggered by `dispatchAction`.
Implementation: if a component implements `Component['findHighDownDispatchers']`,  dispatcher elements by a given name will be found and this feature is enabled.
(4) Some refactor.

(1) add missing test:visual
(2) fix tooltip component default position: should apply `position` on option firstly.

fix(custom): fix series label on custom series not working properly. close #14092

(1) fix contain point calculation.
(2) remove Geo['_nameCoordMap'], instead, calculate center on demand.
(3) fix that some API missing nameProperty and geoJSON should cached not only by mapName but also by nameProperty.
(4) do not support nameMap in geoSVG until some real requirements come.
(5) svg line polyline use 'region.lineStyle' rather than 'region.itemStyle'
(6) svg text tspan image are enabled to trigger tooltip and user event (but not supported to change state and style yet).

perf(tooltip): improve the performance of tooltip.

feature: [tooltip] correct component tooltip cascade and support manually trigger component tooltip.

(1) Make component tooltip inherit cascade correct: itemOption.tooltip -> componentOption.tooltip -> globalOption.tooltip
(previous incorrect cascade: itemOption.tooltip -> globalOption.tooltip
(2) Enable trigger component tooltip by chart.dispatchAction({ type: 'showTip', legendIndex: 0, name: 'some' });

To make (2) happen, this commit migrate `ECElement['tooltip']` to ECData['tooltipConfig']['option'],
and add other info in ECData['tooltipConfig']:
{
      componentMainType
      componentIndex
      name
}
to locate a tooltipable component element by a payload.

feat(i18n): added czech translation

(1) "geoselectchanged" event: add param: allSelected: { geoIndex: number, name: string[] }[]
(2) geoSVG resource support:
+ label
+ emphasis/select/blur state
+ "geoselectchanged" event (on geo component)
+ "selectchanged" event (on map series)
(3) some refactor to make those happen:
+ The original `Region` is migrated to `GeoJSONRegion`. And make `Region` as the base class of `GeoJSONRegion` and `GeoSVGRegion`.
+ Modify the constructor of `Geo`.

(1) label scale implementation change: user afterUpdate rather than / parentScale.
(2) some refactor and clean code.

* fix(series): fix series data type judgment bug. close #14293

* fix(series): fix series data type judgment bug. close #14293

* fix(style): change code style

* fix(remove files): remove history files

Fix(sankey): sankey label has higher z2

(1) refactor of geoJSON & SVG source loader and management.
(2) remove the support of "load multiple geoJSON or SVG in one map name". This feature is never documented and published. And this feature have a inherent problem that it's not easy to normalize the unit among the different SVG. After this commit, one map name can only have one geoJSON or one SVG.

fix(dataZoom):fix dataZoom setting no effect
