Allow passing array of globs to `expandGlob`/`expandGlobSync`

**Is your feature request related to a problem? Please describe.**

I'm creating an API which will take in an `include` and `exclude` array of files. Wanted to mirror APIs like the one typically used in [tsconfig](https://www.typescriptlang.org/tsconfig#include). Currently I have to run an `expandGlob` for every member of my `include` array.

`expandGlob` already allows an `exclude` option which takes in an array, so it seems a bit odd to me that is not the case for the input `glob` itself.

**Describe the solution you'd like**

Ideally, I'd like to simply pass an array of globs into `expandGlob`. Something like this:

```typescript
expandGlob(glob: string | string[] | URL, options: ExpandGlobOptions)
```

**Describe alternatives you've considered**

- **Add `include` into options** - This doesn't seem correct though, since `glob` is essentially `include`, but with one item.
- **Create a new separate function specifically for glob arrays** - Open to this if it will completely change the mechanism, but it seems less than ideal to me
