RFR: 8311517: Add performance information to ArrayList javadoc [v2]

[dan1st]

> The [JEP for sequenced collections](https://openjdk.org/jeps/431) would add addFirst(), removeFirst() and reversed() methods to lists.
> However, the Javadoc of List mentions:
>  > The size, isEmpty, get, set, iterator, and listIterator operations run in constant time. The add operation runs in amortized constant time, that is, adding n elements requires O(n) time. All of the other operations run in linear time (roughly speaking). The constant factor is low compared to that for the LinkedList implementation.
> 
> This PR updates that Javadoc to factor in the new methods introduced by JEP 431.
