feat: Log indexing system to improve eth_getLogs performance (EIP-7745)

[SkandaBhat]

(WIP; please expect a lot of changes before its ready for review!)

Implements a dedicated log indexing system based on EIP-7745 using FilterMaps to replace bloom filters for eth_getLogs queries, providing significant performance improvements.

Fixes #16999

Summary

This PR introduces a new log indexing system based on FilterMaps (sparse bit maps) that dramatically improves the performance of log queries. The implementation follows the EIP-7745 specification and includes:

• reth-log-index crate with core algorithms for indexing and querying
• A new IndexLogs stage for building the index during sync
• RPC integration with hybrid query mode (indexed + bloom filter fallback)
• Database tables for FilterMapMeta, FilterMapRows, and LogValueIndices

Testing

On Sepolia, for 100k blocks query for WETH transfers on my local machine, I got ~2x improvement:

Method	Cold cache	Warm cache
Bloom filter	7.148s	0.554s
Indexed	3.958s	0.285s
