LibWeb: Do not blindly create File objects when adding FormData entries

Browse source 
We were unconditionally creating new File objects for all Blob-type
values passed to `FormData.append`. We should only do so if the value is
not already a File object (or if the `filename` attribute is present).

We must also carry MIME type information forward from the underlying
Blob object.
