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.

首先追蹤 build、serve、test 和 e2e 命令中的資產處理，因為 issue 回報了它們之間存在不同的行為。定義萬用字元輸入路徑應如何決定複製根目錄，並驗證所要求的資產是否在不產生不需要的中間資料夾的情況下完成複製。完成標準是，萬用字元路徑對列出的命令都能一致運作，包括 serve 輸出。
