Report a warning/error when multiple instance of `@angular/core` are bundled.

### Command

build

### Description

When the CLI bundles Angular apps it can happen that multiple instances of `@angular/core` are bundled.

This leads to a variety of errors at runtime that are difficult to diagnose for developers.

Currently on the FW repo we point users toward : angular/angular#35586

### Describe the solution you'd like

I'd be great if the CLI could throw a warning/error when it happens so users are aware even before runtime that there is an issue with their bundle and they should have a look at their dependency resolution !

從 CLI 的 build 命令開始，調查相依性解析和打包的 Angular 應用程式在 build 期間是如何表示的。查看 angular/angular#35586，了解回報的多個 @angular/core 執行個體故障模式。當多個執行個體被打包時，build 能在執行階段故障發生前回報警告或錯誤，即視為完成。
