Adding custom cursor properties for Treemap

• Can maps support custom cursor style? #13632

Before: What was the problem?

In treemap, there is no way to customize the cursor style through cursor, and it can only default to "pointer"

Users can set the cursor style in option like other series graph

series: [
 {
    name: 'TreeMap Cursor',
    type: 'treemap',
    label: ... ,
    breadcrumb: ... ,
    levels: ... ,
    cursor:'crosshair',  // it should be able to set crosshair for treemap
    data: 
  }
]
