An updated OLMo model will be released in November. The new model has a few small architecture changes compared to the existing model in transformers:

- RMSNorm is used instead of standard layer norm.
- Norm is applied to attention queries and keys.
- Norm is applied after attention/feedforward rather than before.

The original PR https://github.com/huggingface/transformers/pull/34497 updated the OLMo implementation in transformers to support the November release. This PR instead adds a new model using the modular approach.

Comments:
I tested this before we locked in the `Olmo1124` naming conventions. Will update once tested.

Tests are passing, including slow ones (except for `Olmo1124ModelTest::test_generate_compile_1_end_to_end`, but this appears to be broken for base OLMo too so I'm considering it an existing problem).. I've used a test HF hub repo ([shanearora/OLMo-7B-1124-hf](https://huggingface.co/shanearora/OLMo-7B-1124-hf)) since the official final model is not ready yet.

PR checks were passing before I merged main again, and PR check failures relate to other models.

@ArthurZucker Gentle ping

The docs for this PR live [here](https://moon-ci-docs.huggingface.co/docs/transformers/pr_34551). All of your documentation changes will be reflected on that endpoint. The docs are available until 30 days after the last update.

Something has gone wrong with the rebasing it seems 😓 

We can merge once this is fixed!

I'm just going to add something for the model card (better than the blank state it is, we can change it later).
