[Chassis] Update lossy profile to restrict buffer usage in congestion…

… state (#20132) Why I did it This change is to restrict lossy queue buffer usage in case of congestion state. Work item tracking Microsoft ADO (29315559): How I did it Updated alpha from 0 to -4 (400g) & -5 (100g) port speed. This configuration is applied on system port and will be using HWSKU port speed settings. How to verify it It is verified using sonic-mgmt tests and running ok.
