net: wget: add definition of struct wget_http_info

The struct wget_http_info exposes the HTTP information of the last HTTP
request issued by wget, and it controls whether the efi bootdevice is set,
and whether the buffer size needs to be checked (lwip stack only). This
information is otherwise discarded. The wget_http_info struct can be used
by HTTP drivers to have more control over HTTP requests.
