Add support for running openHAB with Java 21

Today Java 21 will be launched. 🚀 This is a LTS release, so we should also support using it with openHAB.

We can use this issue to keep track of what still needs to be fixed or investigated (similar to #1316).

There's also a launch live stream: https://dev.java/community/java-21-launch/

It seems that official Java 21 releases are delayed (see Temurin blog).

Nevertheless I was able to use the Temurin 21-beta+34-202308082331 nightly build and got OH 4.1.0-SNAPSHOT running without issues so far after disabling the recently added Java compatibility check.

It seems the recent Karaf 4.4.4 upgrade helped a lot because OH 4.0.3 does not start with Java 21:

We might also want to upgrade Netty to 4.1.99.Final or newer because it can crash the JVM, see:
