[Private Network Access] Add feature switch for reducing longest waiting time for PNA preflight response.
Some servers never respond to the preflight requests which makes the preflight request wait forever and the main request never send. While PNA preflight is currently under warning only mode, we would like to reduce the impact for users, so that we added a special shorter timeout limit (200 milliseconds) to PNA preflight requests previously. However, several user reports show that they are willing to have the possibility to remove the special limit and have a full-functional test of the usage.
