### Description We are currently using Murmurhash 2([MurmurHash64.java](https://github.com/apache/lucene/blob/main/lucene/codecs/src/java/org/apache/lucene/codecs/bloom/MurmurHash64.java)) in the bloom filters implementation in lucene where we also have Murmurhash 3 (the latest one available in the [MurmurHash](https://en.wikipedia.org/wiki/MurmurHash) family of hash functions) and provides better performance, avalanche effect etc. It provides 128-bit variant which Murmurhash 2 doesn't. This PR aims to use Murmurhash 3 with bloom filters and see if that helps. Note : We are already using murmur hash 3 in [BytesRefHash](https://github.com/apache/lucene/blob/main/lucene/core/src/java/org/apache/lucene/util/BytesRefHash.java#L412-L414) implementation (#6666) Next steps : Run `luceneutil` benchmarks and share the results <!-- If this is your first contribution to Lucene, please make sure you have reviewed the contribution guide. https://github.com/apache/lucene/blob/main/CONTRIBUTING.md --> -- This is an automated message from the Apache Git Service.
