## Motivation
Fix roctx range markers (Push/Pop, Start/Stop) not being displayed correctly in rocpd output. The Visualizer was showing only Stop/Pop events as instant markers instead of proper duration ranges with labels, while Perfetto output displayed them correctly.
## Technical Details
In `tool_tracing_callback_stop()`, the rocpd/database output was using `user_data->value` (timestamp of the Pop/Stop event) instead of `begin_ts` (corrected timestamp from the corresponding Push/Start event) when calling `cache_region()`.
The Perfetto output already used `begin_ts` correctly (line 818). This change aligns the rocpd output with the Perfetto behavior by using `begin_ts` instead of `user_data->value` (line 887).
Updated rocpd validation rules
* Forward ctest labels from the execution test to the validation test.
* Adjust test validation parameters for amid_smi samples
The actual number of samples will vary depending on the GPU. This test
is just to validate the presence of the samples
