Add ATECC608 simulator

[LinuxJedi]

Currently has patches to work around minor wolfCrypt issues. These will be fixed in wolfCrypt at the same time this is added to the CI.

Pull request overview

Adds a new Microchip ATECC608A secure-element simulator to this repository (alongside existing simulators), including a Rust TCP server implementing a wolfSSL/cryptoauthlib-required ATCA command subset, plus Dockerized integration tests and GitHub Actions workflows to run them in CI.

Changes:

• Introduce ATECC608Sim/atecc608-sim: Rust simulator library + TCP server, object-store persistence, and unit/integration tests.
• Add sdk-test (cryptoauthlib + OpenSSL cross-verification) and wolfcrypt-test (wolfCrypt suite harness) Docker test tiers.
• Wire new CI workflows to build/run the simulator and both integration test images on PRs.
