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!

_No response_

### Describe alternatives you've considered

https://github.com/nrwl/nx/blob/master/packages/angular/src/executors/application/application.impl.ts

Beginne damit, den Einstiegspunkt des Angular application builder zu lesen und sein Verhalten mit nx/packages/angular/src/executors/application/application.impl.ts, der in der Issue verlinkten Implementierung, zu vergleichen. Verfolge, wie Build- und Serve-Optionen behandelt werden, und überprüfe anschließend, dass plugins und indexHtmlTransformer für beide Workflows konfiguriert werden können und dass die vorhandenen application-builder-Tests das vollständige Verhalten abdecken.
