amd_smi: fail on unexpected add/start errors

[djwoun]

Pull Request Description

Updates EXIT_WARNING_ON_ADD to treat unexpected error codes (e.g., PAPI_EISRUN, PAPI_EINVAL) as test failures. Previously, non-listed errors were silently ignored, causing tests to pass incorrectly.

[Treece-Burgess]

Testing was done on Odyssey at Oregon with ROCm 7.2.0.

In the master branch, if the call prepare_event_handle failed with an error code outside of PAPI_ENOEVNT, PAPI_ECNFLCT, PAPI_EPERM, or PAPI_ENOSUPP the test would pass:

[tburgess@odyssey tests]$ ./amdsmi_set_test 
Skipping fan_speed test: event unavailable
PASSED

However, this branch updates this to the correct behavior:

[tburgess@odyssey tests]$ ./amdsmi_set_test 
Unexpected error encountered (-24) when adding the event amd_smi:::power_cap.

Along with this, papi_component_avail, papi_native_avail, and papi_command_line work as expected.
The amd_smi component tests all pass (minus amdsmi_set_test.c as I lack the permissions to properly run this test).
