TrigGpuTest fixes
Fix test definition now that threads must be set explicitly (!65066 (merged)). Install tests.
Improve error diagnostics if CUDA fails. Example output:
TrigInDetAccelerationSvc 0 INFO TrigInDetAccelerationSvc: initialize
ERROR: CUDA driver version is insufficient for CUDA runtime version
No CUDA devices found
TrigInDetAccelerationSvc 0 INFO OffloadFactory config failed
TrigFastTrackFinder_beamSpot 0 ERROR TrigFastTrackFinder/src/TrigFastTrackFinder.cxx:250 (StatusCode TrigFastTrackFinder::initialize()): code FAILURE: m_accelSvc->isReady()
Closes ATR-28368
