RFR: 8303216: Prefer ArrayList to LinkedList in sun.net.httpserver.ServerImpl

Sun Feb 26 20:19:41 UTC 2023

LinkedList is used in a few places in `ServerImpl`.
There is only add/iterator/clear/size calls on this lists. No removes from the head or something like this. ArrayList should be preferred as more efficient and widely used (more chances for JIT) collection.
