feat: improved eigenlayer context and testing

[Tjemmmic]

Overview

This PR focuses on improvements to the EigenLayer blueprints through the following changes:

• Better, more reusable test utilities for EigenLayer blueprints
• Creates bindings for our common Eigenlayer Contracts to avoid issues with relative paths
• Moves the EigenLayer Incredible Squaring Blueprint test from the test-utils crate into the blueprint
• More methods automatically implemented via the Eigen Context
• Tests/examples for the context functions

Looks good, some changes to fix and improve. Naming needs improvement, it feels robotic. Some test util function for eigen environment should not have been removed IMO as it's a reusable eigen environment system.

I suggest creating methods to craft the Eigenlayer specific settings (and other protocols) so that this isn't the finished product. There are blueprint_id/service_id in this that shouldn't be expected to be supplied by end developers. Same with Symbiotic contract data.

[drewstone]

i.e. let config = ContextConfig::create_eigenlayer_config(...)

Also why is blueprint/service id even Some? Shouldn't it be None?
