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!

首先阅读 Angular application builder 的入口点，并将其行为与 issue 中链接的实现 nx/packages/angular/src/executors/application/application.impl.ts 进行比较。跟踪 build 和 serve 选项的处理方式，然后验证 plugins 和 indexHtmlTransformer 是否都能为两种工作流进行配置，以及现有的 application-builder 测试是否覆盖了完成后的行为。
