fix: log eigenvalue monitor values (#8049)
## Summary
- replace the nonexistent `self.ev_values` reference in eigenvalue
monitor logging
- avoid indexing the `dict_values` view returned by
`self.block_eigenvalue.values()`
- add a small regression helper/test for the event payloads
Fixes #7983.
## To verify
- `python -m py_compile deepspeed\runtime\engine.py
tests\unit\runtime\test_engine_eigenvalue.py`
- `git diff --check`
- AST-extracted helper smoke test: passed
I also tried `python -m pytest
tests\unit\runtime\test_engine_eigenvalue.py -q` on this Windows
checkout. Collection failed before the test body because the local
package import resolves `deepspeed.accelerator` differently in this
clone/environment. The touched code and the helper itself both compile,
and the helper smoke test exercises the exact event construction without
importing the full package.
