Feature request: add indexHtmlTransformer and plugins options to application builder

### Command

build

### Description

Hi. This feature exists for a long time in angular-builders and nx custom builders' code.
`plugins` allows adding vite plugins; we use this option to use custom plugin with .env file parsing, adding ENVIRONMENT_NAME and __APP_VERSION__ global variables and much more. I guess there are plenty of other use-cases for this.
`indexHtmlTransformer` allows to replace some placeholders in index.html while building or serving an app. Useful to make similar DX when building or developing locally my app.

There is [not much to do](https://github.com/nrwl/nx/blob/master/packages/angular/src/executors/application/application.impl.ts) with these two, but i think this will boost DX many times.
Thanks for your time!

まず Angular application builder のエントリーポイントを読み、issue でリンクされている実装である nx/packages/angular/src/executors/application/application.impl.ts と動作を比較します。build と serve のオプションがどのように処理されるかを追跡し、続いて両方のワークフローで plugins と indexHtmlTransformer を設定できること、また既存の application-builder テストが完成した動作をカバーしていることを確認します。
