What does this PR do ?

Added adaptive muon and test.

Clean up some emerging optimizers code overall

A further update of _init_group is required from EmergingOptimizers side before distributed checkpoint can be supported.
Coresponding change: https://github.com/NVIDIA-NeMo/Emerging-Optimizers/pull/132/changes

Recommend to finish EmergingOptimizers update and pick it up in dev before merging to main branch.

⚠️ For major changes (either in lines of code or in its impact), please make sure to first share a design doc with the team. If you're unsure what's the best way to do so, contact the @mcore-oncall.
