As suggested in ATR-28571, this MR:
* renames test_trigP1_v1PhysP1_trfDbgStream_build.py to test_trigP1_v1PhysP1_trfDbgStreamData21_build.py
* test_trigP1_v1PhysP1_trfDbgStream_build.py is introduced with a similar setup, based on a data24 test file ('data' was renamed 'data24' for clarity), and a step is moved to CA (thresholds in info/warning/other messages are adjusted so the test runs successfully)
The new file has been copied to EOS.

Cheers,
Bertrand
