feat: Port ReadPrecompileCalls struct from node-builder to main

- Add ReadPrecompileCalls struct to hyperliquid-types with helper methods
- Update BlockAndReceipts to use the new struct type
- Remove duplicate collect_block and BlockAndReceipts from evm/lib.rs
- Refactor EVM factory to avoid collect_block overhead during EVM creation
- Clean up unused imports (SealedBlock, Serialize, Deserialize)

This fixes issue #24 by removing the duplicate collect_block that caused
overhead during transaction tracing. The EVM factory now only reads from
the precompiles cache instead of loading block data on every EVM creation.
