Remove option support-regular-ptr

[etiotto]

This PR removes the now obsolete option "support-regular-ptr" from the pipeline pass registration and related transformation functions. Key changes include:

• Updating the pipeline pass registration macro in triton_xpu.cc to drop the extra parameter.
• Removing the bool supportRegularPtr parameter from function signatures and calls in SoftwarePipeliner.cpp and MatmulLoopPipeline.cpp.
• Adjusting the declaration in Schedule.h to match the updated function signature.

• Verify that the updated macro call now requiring only an int parameter (instead of int, bool) for createTritonIntelGPUPipeline is consistent with downstream expectations.

• Ensure that all call sites for pipelineLoop have been updated to omit the removed supportRegularPtr parameter.

• Confirm that the removal of the supportRegularPtr argument from both collectOpsToPipeline and preProcessLoopAndGetSchedule aligns with the overall pipeline transformation logic.
