deprecate node.on(type: string) and use node.on(type: NodeEventType) instead

[PPpro]

I've tried deprecated like this

but it seems the ts language service cannot distinguash the enum and string type,

I guess it is because the NodeEventType enum value is string

enum NodeEventType {
  MOUSE_DOWN = 'mouse-down'
}

we should support compile cc.d.ts to

enum NodeEventType {
  MOUSE_DOWN
}

so that the ts can distinguash the enum and string type, and this is what we expect
