Add property to hide the Expand/Collapse tooltip

We currently don't have a property to not display the expand/collapse tooltip of the TaskBoard.

Currently, we have:

dataset : {
   btip : StringHelper.xss`${this.L(collapsed ? 'L{TaskBoard.expand}' : 'L{TaskBoard.collapse}', text)}`
}

Suggestion: We could have like a hideCollapseTooltip property, and then:

dataset : !hideCollapseTooltip ? {
   btip : StringHelper.xss`${this.L(collapsed ? 'L{TaskBoard.expand}' : 'L{TaskBoard.collapse}', text)}`
} : null
