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.

Comece rastreando o tratamento de assets nos comandos build, serve, test e e2e, pois a issue relata comportamentos diferentes entre eles. Defina como os caminhos de entrada com wildcard devem estabelecer a raiz de cópia e verifique se os assets solicitados são copiados sem pastas intermediárias indesejadas. Está concluído quando o caminho com wildcard funcionar de forma consistente para os comandos listados, incluindo a saída de serve.
