`transform` and `through` are removed in 4.0. Since users cannot
reference them in 4.0 document, it's not good to keep using them as
example in `repartition` description.

Use "incompatible" instead of an empty cell in Kafka Streams broker
compatibility docs. Also update compatibility matrix for 4.0.0 release.

Pull request to implement KIP-1111, aims to add a configuration that
prevents a Kafka Streams application from starting if any of its
internal topics have auto-generated names, thereby enforcing explicit
naming for all internal topics and enhancing the stability of the
application’s topology.
- Repartition Topics:
All repartition topics are created in the
KStreamImpl.createRepartitionedSource(...) static method. This method
either receives a name explicitly provided by the user or null and then
builds the final repartition topic name.
- Changelog Topics and State Store Names:
There are several scenarios where these are created:
In the MaterializedInternal constructor.
During KStream/KStream joins.
During KStream/KTable joins with grace periods.
With key-value buffers are used in suppressions.

Most of the changes are obvious clean-ups/fixes. A couple of noteworthy items:
1. Support for non LTS versions is clarified (we were incorrectly stating full support
for Java 23).
2. TLS version negotiation details are clarified.

This PR upgrades RocksDB from 7.9.2 to 9.7.3 and addresses the following compatibility issues introduced by the RocksDB upgrade:
- Removal of AccessHint: The AccessHint class was completely removed in RocksDB 9.7.3. This required removing all import statements, variable declarations, method parameters, method return types, and static method calls related to AccessHint in RocksDBGenericOptionsToDbOptionsColumnFamilyOptionsAdapter.java RocksDBGenericOptionsToDbOptionsColumnFamilyOptionsAdapterTest.java Unused methods are removed in RocksDBGenericOptionsToDbOptionsColumnFamilyOptionsAdapter.java
- Removal of NO_FILE_CLOSES: The NO_FILE_CLOSES metric was also removed in RocksDB 9.7.3. The calculation for numberOfOpenFiles in RocksDBMetricsRecorder.java has been adjusted to now track the total number of file opens since the last reset. The previous calculation, which subtracted NO_FILE_CLOSES from NO_FILE_OPENS, is no longer possible. The reason RocksDB removed NO_FILE_CLOSES seems to be that it did not properly work: https://github.com/search?q=repo%3Afacebook%2Frocksdb+NO_FILE_CLOSES&type=issues
- Removal of methods related to compressed block cache configuration in BlockBasedTableConfig
- Change of the signature of org.rocksdb.Options.setLogger()
