RFR: 8253178: Replace LinkedList Impl in net.http.FilterFactory [v2]

[Sergei Ustimenko]

> This patch replaces a LinkedList data structure used in the net.http.FilterFactory class with an ArrayList. This issue relates to [JDK-8246048: Replace LinkedList with ArrayLists in java.net.](https://bugs.openjdk.java.net/browse/JDK-8246048).
> 
> The list created once per HttpClient and filled with upfront known values (3 of them in the jdk.internal.net.http.HttpClientImpl#initFilters: AuthenticationFilter.class, RedirectFilter.class and depending on the presence of a cookieHandler - a CookieFilter.class).
