Implement build.rs bindings generation

[jmg-duarte]

Description

Implements bindings generation in build.rs, adding this allows

1. Generated code to be inspected manually and "cmd-click"ed into
2. Faster incremental compilation since the code can be cached unlike macros

Changes

• New contracts-generate crate to simplify build.rs code
• Generate bindings in contracts build.rs
• Migrate everything without changing any module paths
• Moved away from the Provider re-export (contracts::alloy::Provider -> alloy::providers::DynProvider)
• Removes the ethcontract re-export from the contracts crate
• Removes now unused code (some inconsistent tests and dummy legacy things)

How to test

Run existing tests & compile

I have no clue how to review this other than by asking AI.

[jmg-duarte]

I can do them one by one. I did this whole with AI too and did multilple rounds with different contexts. But this was more about proving that I was able to migrate everything with minimal changes on the main codebase

Pull Request Overview

This PR refactors contract binding generation to use a build script approach with auto-generated code. The migration moves from runtime contract instance creation to compile-time code generation.

Key changes:

• Introduces contracts-generate crate with custom binding generation
• Replaces runtime InstanceExt trait with compile-time generated deployment info
• Removes legacy web3 dummy transport and macros
• Updates type references from contracts::alloy::Provider to alloy::providers::DynProvider

Looks nice with the build stuff being part of the contract crate now.
