Contracts: enable IR compilation pipeline with Foundry

[jaybuidl]

Related to #1926.

Performance was the main issue for not adopting it earlier, but it has been significantly improved in recent versions.

Benefits

• More aggressively optimized for gas usage and bytecode size
• More efficient for complex logic and large scale projects
• Better debugging information and error messages

Currently the Vea contracts dependency is holding us back to v0.8.24 which is more sensitive to Stack Too Deep errors. Configuring Foundry for multiple solc versions is not trivial.
