Do not require BIN for abigen

[mkysel]

Remove binary file requirements from abigen script and eliminate contract deployment functionality from generated Go bindings

The changes remove binary file (.bin.json) handling from the contract code generation process and eliminate deployment functionality from all generated Go contract bindings:

• Modified dev/gen/abi script to remove binary file downloading and the --bin parameter from go tool abigen command
• Removed Bin fields, binary variables, and Deploy* functions from seven contract bindings: GroupMessageBroadcaster, IdentityUpdateBroadcaster, NodeRegistry, PayerRegistry, PayerReportManager, RateRegistry, and SettlementChainParameterRegistry
• Generated Go bindings now only contain ABI-based functionality for interacting with existing contracts, not deploying new ones

📍Where to Start

Start with the dev/gen/abi script to understand how the binary file requirements were removed from the code generation process.

Walkthrough

This change removes all deprecated contract deployment functions and associated compiled bytecode variables from several Ethereum contract binding packages. The affected packages now only provide bindings for interacting with already deployed contracts, and no longer support deploying new contract instances directly through their Go APIs.
