new library public-api.ts file not using component type declared on angular.json's schematics

### Which @angular/* package(s) are the source of the bug?

Don't known / other

### Is this a regression?

No

### Description

When I create a new library the default component inside of the lib folder takes its type from the component schematic declared on angular.json. If for example my angular.json looks like this:
```
{
//...
"newProjectRoot": "projects",
//...
"schematics": {
"@schematics/angular:application": {
"style": "scss",
"inlineTemplate": true,
"inlineStyle": true,
"ssr": false
},
"@schematics/angular:component": {
"changeDetection": "OnPush",
"type": "Cmp",
"inlineStyle": true,
"inlineTemplate": true,
"style": "scss"
}
}
}
```

After creating a library using `ng generate library foo-library`, the new library includes an empty dummy `FooLibraryCmp` inside the `projects/foo-library/src/lib/foo-library.cmp.ts`. However, the contents of `projects/foo-library/src/public-api.ts` look like this:

```
/*
* Public API Surface of foo-library
*/

export * from './lib/foo-library.service';
export * from './lib/foo-library.component'; // uses .component instead of .cmp
```

### Anything else?

首先，在 `angular.json` 中使用 `@schematics/angular:component` 的 `type` 设置重现 `ng generate library foo-library`，然后检查生成的 `projects/foo-library/src/lib/foo-library.cmp.ts` 和 `projects/foo-library/src/public-api.ts`。当 `public-api.ts` 使用已配置的文件名后缀而不是 `.component` 导出生成的组件时，即表示完成。
