[FLINK-16686][State] Set classloader for compaction filters

[Zakelly]

What is the purpose of the change

The RocksDB/ForSt 's list state use the user serializer to deserialize the list elements and filter the expired ones during compation. But the compaction runs in background threads that the RocksDB/ForSt allocated. These native threads do not have the JVM context, which is problematic when invoking some serializers that require JVM capabilities, such as Kryo that uses the classloader. Multiple issues have been reported: https://stackoverflow.com/questions/67321286/flink-application-fails-when-rocksdb-list-state-is-cleaned-by-ttl

This PR captured the user classloader from the thread that uses to create the compaction filter factory, and pass that to the native threads, solving the problem above.

Brief change log

• Change the ListElementFilterFactory taking the current thread's classloader and pass it to the created ListElementFilter later.
• Add thread-local initializer to set classloader and duplicate serializer in ListElementFilter.
• Add same logic above for ForSt as well as RocksDB
• Add tests.
