Add Value link from AsyncFile to File

If type has value there is Value link which points from type to `String|Number|Object`. We should do the same for `File`

Right now there is no `Value` link that points from `AsyncFile` type
```js
await deep.select({
from_id: await deep.id("@deep-foundation/core", "AsyncFile"),
type_id: await deep.id("@deep-foundation/core", "Value")
})
{data: Array(0), loading: false, networkStatus: 7}
```

Locate the definitions or setup for the AsyncFile and File types, then inspect how the existing Value links for String, Number, and Object are created. Verify the expected relationship by running the shown deep.select query for AsyncFile and Value; done means it returns the corresponding link instead of an empty array.
