Description

### Search before asking

- [x] I searched in the [issues](https://github.com/apache/fluss/issues) and found nothing similar.

### Motivation

Currently, prefix bloom filters are not configured in the underlying RocksDB, which causes the PrefixLookup operation to perform heavy seek operations, resulting in significant CPU&IO overhead.

### Solution

RocksDB already supports prefix bloom filters, and we should enable this configuration to improve PrefixLookup performance.

See: https://github.com/facebook/rocksdb/wiki/Prefix-Seek#configure-prefix-bloom-filter

### Anything else?
