Implement Warp intrinsic gas via libevm hooks

[ceyonur]

Why this should be merged

We need to adhere warp intrinsic gas charges in SAE. We have discovered that IntrinsicGas in Coreth and Subnet-EVM potentially charges less gas than the original upstream implementation (see #5194). We have added relevant hooks to libevm. This PR implements the hook in Coreth + Subnet-EVM that will replace the IntrinsicGas implementation in core package.

How this was tested

UTs + test PR

Need to be documented in RELEASES.md?

No

This PR should not be merged until ava-labs/libevm#282 is merged

Pull request overview

This PR switches Coreth and Subnet-EVM to use libevm/core.IntrinsicGas (with newly added libevm hook support) to ensure Warp intrinsic gas is charged consistently with upstream behavior, and wires Avalanche-specific access list/predicate gas logic through the libevm hooks layer.

Changes:

• Replace in-repo core.IntrinsicGas usage/implementation with libevm/core.IntrinsicGas across Coreth + Subnet-EVM execution, txpool validation, predicate checks, and block verification.
• Add a RulesExtra.AccessListGas hook implementation (Coreth + Subnet-EVM) to preserve predicate-based access list intrinsic gas accounting.
• Bump github.com/ava-labs/libevm dependency and update Bazel deps to include the needed libevm packages.

I don't see any behavior change, so good with me. I left a nit that applies to all the files
