text: Title: Support for setting partitioned cookies
  Body: ### Is your feature request related to a problem?
  
  I need to use partitioned cookies to set cookies in contexts where third-party cookies are otherwise restricted.
  
  ### Describe the solution you'd like
  
  A recent addition to the Set-Cookie header is the ability to mark cookies as partitioned (see https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Set-Cookie#partitioned, https://developer.mozilla.org/en-US/docs/Web/Privacy/Privacy_sandbox/Partitioned_cookies).
  
  `StreamResponse.set_cookie` should support setting partitioned cookies, e.g. using a `partitioned=True` keyword argument.
  
  ### Describe alternatives you've considered
  
  I can create a 'Set-Cookie' header manually, but would have to figure out edge cases with encoding and escaping special characters myself. This would be inconvenient and probably error-prone.
