### What this PR does / why we need it?
Add ACL graph capture/replay DP test, this is a imprved version of #3886
Restructures the multi-card ACL graph test for improved clarity,
robustness, and accuracy.
Key improvements include:
- Replaces fragile `sys.settrace` and manual patching with a clean,
reusable spy installer using `unittest.mock.patch`.
- Introduces more precise metrics by tracking
`NPUModelRunner.execute_model` and `_dummy_run` calls directly.
- Rewrites assertions to be more accurate and provides clear
explanations for the expected counts of graph captures, replays, model
executions, and dummy runs.
- Simplifies the overall test structure by separating the worker logic
into a dedicated function.
- Removes a long, unnecessary sleep at the end of the test.
- Expands test coverage by adding a larger `max_tokens` parameter.
### Does this PR introduce _any_ user-facing change?
None.
### How was this patch tested?
None.
