Closes #1740, Closes #2002

Unfortunately JS's fetch API is somewhat limited and only supports two
options for multipart form data parts:

  1. String with no file name and no mime type (which should be
    interpreted as text/plain).
  2. Blob with a file name ("blob" if not provided by the user) and a
    mime type if provided by the user.

Until this commit, reqwest always used the latter option, so when a user
tried to add a text part with no file name, it would be sent with a mime
type of application/octet-stream and the filename "blob".

While we can't make the behaviour identical to the native
implementation, we can do a best-effort approach, using option (1) as
long as the user hasn't set a file name or a non plain text mime type.
