[3.3] Upgrade HashedWheelTimer with the same class of latest Netty 4.2

[zrlw]

What is the purpose of the change?

1. Upgrade HashedWheelTimer content based on latest Netty's HashedWheelTimer(Oct 17, 2025): https://github.com/netty/netty/blob/d7b39b4f48aff9f7efd2fe0aa8841e2aa13e2874/common/src/main/java/io/netty/util/HashedWheelTimer.java (https://github.com/netty/netty/commit/d7b39b4f48aff9f7efd2fe0aa8841e2aa13e2874)
2. Add jctools-core to transitive dependencies of dubbo-all and dubbo-all-shaded because latest Netty's HashedWheelTimer took MpscQueue of jctools-core as its queue but all dubbo sub-modules dependency optional flag are set to true.
3. This pr includes https://github.com/apache/dubbo/pull/15755 since latest Netty's HashedWheelTimer contains a lot of codes that calls sun.misc.Unsafe.
