multipart/form-data for a list of byte[]

**Describe the issue**

Having something like this:
`
public class FileModel {
public byte[] File {get; set;}
}
`

When the type is a List the example generated in swagger ui shows like it was an application/json request, but when it is just FileModel it displays the ui for pick a file from your disk.

Also, when you set the type to just byte[], the ui displays it as a text instead of a file upload control.

**Expected behavior**
Swagger ui renders multiple file upload when having List. It also displays file upload for byte[]

Start by reproducing the models described in the issue and inspect the OpenAPI generation path and resulting Swagger UI schema for FileModel, List, and byte[]. Compare the generated request content types and file controls. Done means multipart/form-data renders the appropriate single or multiple file uploads, including for byte[].
