Support cursor option in brush

[peder1001]

What problem does this feature solve?

I would like to use the brush to select an area of the chart.
I would not like the cursor when using the brush to be a crosshair, I would rather it be a regular pointer.

Therefore I suggest adding a cursor option to the brush object so that the developer can set the brush cursor themselves.

https://echarts.apache.org/en/option.html#brush

What does the proposed API look like?

brush:
{
xAxisIndex: 'all',
brushLink: 'all',
cursor: 'pointer', // new option
brushType: 'lineX',
brushMode: 'single',
transformable: false,
removeOnClick: true,
cursor: 'wait',
brushStyle: {
borderWidth: 0,
color: 'rgba(255,255,255,0.01)',
},
outOfBrush: {
colorAlpha: 0.4,
color: '#153A59'
}
}

I have the same issue, the brush hot zone is conflict with the click zone, i want to show pointer when the point is hovered, but it shows the cross cause in the brush hot zone, i think it should have a param choice to set the priority.
