[reland][inductor] make thread order consistent with loop order (#107902)
This PR relands https://github.com/pytorch/pytorch/pull/106827 which get reverted because of causing compilation error for some ads model.
Yanbo provide a repro in one of the 14k model ( `pytest ./generated/test_KaiyangZhou_deep_person_reid.py -k test_044`). This is also the model I used to confirm the fix and come up with a unit test. In this model, we call `tritoin_heuristics.triton_config` with size_hints [2048, 2]. Previously this would result in a trition config with XBLOCK=2048 and YBLOCK=2 . But since we change the mapping between size_hints and XYZ dimension, we now generate a triton config with XBLOCK=2 and YBLOCK=2048. This fails compilation since we set max YBLOCK to be 1024.
My fix is to make sure we never generate a triton config that exceeds the maximum block size.
