Pull request overview

Ports EVM LinkToken state loading/view generation logic into this repo to support reading LINK/Static LINK token deployments from an address bundle (TypeAndVersion map), aligning with the CLD changesets/view layer.

Changes:

• Adds LinkTokenState and StaticLinkTokenState with Generate*View helpers.
• Adds MaybeLoadLinkTokenChainState and MaybeLoadStaticLinkTokenState to bind on-chain wrappers from address/type+version inputs.
• Introduces unit tests covering nil bindings, duplicate contract instances, and version mismatch behavior.
