breadcrumb 自动生成面包屑，将NZ_ROUTE_DATA_BREADCRUMB设置为可配置化

[CK110]

What problem does this feature solve?

router data里面的信息可能用于设置为title，和面包屑很大概率上是同一个值

What does the proposed API look like?

通过inject token实现可配置

Translation of this issue:

Breadcrumb automatically generates breadcrumbs, setting NZ_ROUTE_DATA_BREADCRUMB to configurable

What problem does this feature solve?

The information in router data may be used to set to title, and the breadcrumbs are of the same probability on a large probability.

What does the proposed API look like?

Configurable through inject token

Would fix this after the global config service is online.

看了 global config, 它是主要设置的组件属性默认值，但是 NZ_ROUTE_DATA_BREADCRUMB还并 不是属性。我觉得可以改为属性 @Input() nzRouteDataBreadcrumbLabel: string = 'breadcrumb'; 。因为系统中不会有很多地方需要 Breadcrumb吧，没必要还可以全局设置默认值吧？
