For spc4 and above, there is only the lossy buffer, so the buffer for the lossless buffer will be taken by the lossy buffer. If the packet size is too small, the packet number sent to occupy the shared buffer will increase a lot, which will lead to the descriptor being exhausted, so update testQosSaiPgSharedWatermark, testQosSaiQSharedWatermark, and testQosSaiLossyQueue accordingly. 2. Remove the test config of scheduler.block_data_plane, otherwise it might raise yang validation error when do config reload 3. When there is no lossless buffer, return a dump buffer lossless pg profile, and skip tests related to lossless buffer case dynamically 4. Skip fixture reaseAllports for mellanox device, because after qos test is finished, the teardown will do config reload, it will restore the config of ports, we don't need this fixture before running tests. Also it can save 2 minutes 5. list the relevant Prs: sonic-net/sonic-buildimage#20992 sonic-net/sonic-buildimage#21056 sonic-net/sonic-buildimage#20991 sonic-net/sonic-buildimage#21056 sonic-net/sonic-buildimage#21427 sonic-net/sonic-buildimage#21056 sonic-net/sonic-buildimage#21762 Summary: Fixes # (issue) ### Type of change <!-- - Fill x for your type of change. - e.g. - [x] Bug fix --> - [ ] Bug fix - [ ] Testbed and Framework(new/improvement) - [ ] New Test case - [ ] Skipped for non-supported platforms - [ ] Add ownership [here](https://msazure.visualstudio.com/AzureWiki/_wiki/wikis/AzureWiki.wiki/744287/TSG-for-ownership-modification)(Microsft required only) - [ ] Test case improvement ### Back port request - [ ] 202012 - [ ] 202205 - [ ] 202305 - [ ] 202311 - [ ] 202405 - [ ] 202411 ### Approach #### What is the motivation for this PR? update the qos sai test for no pg lossless buffer platform #### How did you do it? update for lossy case and skip test relatd to pg buffer lossless #### How did you verify/test it?
