[elasticsearch] Add paimon-elasticsearch module with ES vector global index support

[CrownChu]

Summary

• Add paimon-elasticsearch module implementing GlobalIndex SPI backed by Elasticsearch vector search
• Support archive-based index packaging (tar.gz) for Paimon file system storage
• Include Lucene directory adapter (ArchiveDirectory, ArchiveBackedIndexInput, ArchiveFlatVectorReader) for reading packed index segments
• Add SLF4J bridge for ES internal logging
• Add benchmarks (Sift1M, Lucene vs ES comparison) and integration tests

Key Components

Component	Description
ESVectorGlobalIndexWriter	Builds DiskBBQ vector index and packs into archive
ESVectorGlobalIndexReader	Reads archived index, supports multi-stage retrieval (coarse + rescore)
ESVectorGlobalIndexer	SPI entry point implementing GlobalIndexer
ESIndexArchiveUtils	Pack/unpack Lucene index segments to/from tar.gz
ESVectorIndexOptions	Configuration options (dimension, metric, ef, numCandidates, etc.)

Test Plan

• Unit tests: ESVectorGlobalIndexTest covers write/read/search round-trip
• Benchmarks: ESVectorBenchmark, Sift1MBenchmark, LuceneVsESBenchmark
