refactor(router): rename "as" to "name" in RouteConfig

BREAKING CHANGE:

This is a rename to make routing concepts easier to understand.

Before:

```
@RouteConfig([
  { path: '/', component: MyCmp, as: 'Home' }
])
```

After:

```
@RouteConfig([
  { path: '/', component: MyCmp, name: 'Home' }
])
```

Closes #4622

Closes #4896
