Add GLM-4 MoE TransformerBridge adapter

[zeotrix]

Adds TransformerBridge support for Glm4MoeForCausalLM, covering the Z.ai GLM-4.5 / 4.6 / 4.7 MoE family.

This includes:

• A new GLM-4 MoE architecture adapter with RMSNorm, RoPE, GQA, Q/K norm, and MoE routing support.
• Registration in the architecture factory, supported architectures package, model registry, and report generation.
• Tiny checkpoint registry verification for trl-internal-testing/tiny-Glm4MoeForCausalLM.
• Unit tests for adapter config, component mapping, weight conversions, registration, and component-test setup.
• Integration parity test against HuggingFace on the tiny checkpoint.
• A small verify_models cleanup guard so non-MPS machines do not call MPS synchronization during CPU verification.

Closes #1404

@zeotrix Great work on this! I had to rebase to dev to resolve some merge conflicts, assuming it passes CI I will merge

Thanks! I appreciate you handling the rebase. I'll keep an eye on the CI results. If any issues or regressions show up, feel free to tag me or assign them to me and I'll investigate.

I try to handle any rebases that touch the supported_models doc, it can get hairy when a lot of people are adding to it at once. It is looking like everything will pass! I will rerun the Bridge_Evals_Demo once Full Coverage completes, which should clear your one failure that was caused by those pesky 429 errors
