Asset copy with wildcard in the input path

# 🚀 Feature request

### Command (mark with an `x`)

```
- [ ] new
- [ x] build
- [ x] serve
- [x ] test
- [ x] e2e
- [ ] generate
- [ ] add
- [ ] update
- [ ] lint
- [ ] xi18n
- [ ] run
- [ ] config
- [ ] help
- [ ] version
- [ ] doc
```

### Description
Currently assets array allows glob with input path, however input path itself does not support wildcards.
Like ./node_modules/@myscope/**/assets/i18n/*
Where ** is any number of unknown libraries (like shared, services, featureabc).

With glob it would also create every folder between @myscope to assets/i18n, instead of copying just the contents of i18n.

### Describe the solution you'd like
The input path allows wildcards to set the root or a flag to only copy contents of the glob result path.

### Describe alternatives you've considered
Node scripts that requires extra steps and wouldn't know if project output is different from dist and it does not work with serve.

Empieza rastreando el manejo de assets en los comandos build, serve, test y e2e, ya que el issue informa de un comportamiento diferente entre ellos. Define cómo las rutas de entrada con wildcard deben establecer la raíz de copia y verifica que los assets solicitados se copien sin carpetas intermedias no deseadas. Se considera terminado cuando la ruta con wildcard funciona de forma coherente para los comandos indicados, incluida la salida de serve.
