HTTP API: Normalize cookies before passing them to Requests.

Requests has its own cookie object in form of `Requests_Cookie`. Therefore we have to convert `WP_Http_Cookie` objects to `Requests_Cookie`.
This introduces `WP_Http_Cookie::get_attributes()` to retrieve cookie attributes of a `WP_Http_Cookie` object and `WP_Http::normalize_cookies()` to convert the cookie objects.

Fixes #37437.
