CookieManager.setAcceptPolicy

Set the cookie acceptance policy of cookie_manager as policy.

Note that ITP has its own way to handle third-party cookies, so when it's enabled, and policy is set to [webkit.types.CookieAcceptPolicy.NoThirdParty], [webkit.types.CookieAcceptPolicy.Always] will be used instead. Once disabled, the policy will be set back to [webkit.types.CookieAcceptPolicy.NoThirdParty]. See also webkit_website_data_manager_set_itp_enabled().
