[CK_TILE] Epilogue chaining (Lwpck 3373) (#2773)
* Epilogue chainer * epilogue chainer with context to share state in between epilogues * chain-able epilogues for cshuffle * clang-format * rebase related changes - Added separate chainer test - clang format * comment resolutions * clang-format * Policy based chaining - basic Policy structure to control blanket looping and barrier placement. - to be extended for fine grianed control - to be modified to move possible auto-compute values and SFC access count to policy * Refactoring as per spec - Introduced epilogue schedule, graph - modified chainer to function with graph and schedule * minor_changes - made functions to overload in the epilogue_graph file * clang-format * Documentation and Comments - Added comments to files - Noted changes in changelog - Added README to explain the chainer and current status, exact use steps to be added * Comment resolutions - README modified with the suggested changes - Comment fixed accordingly * major refactoring - modified the chainer files to match the new design - updated comments - updated readme - multi-d example shocases use of the chainer * minor cleanup * tensor and rowcol quant chainer epilogue - added scalarepilogue for tensor quant - added schedule for tensorquant - modified quant example to use chainer and appropriate schedules * Refactor epilogue chainer: generalize ops and standardize context interface Address review comments. Changes: - Rename CastToLdsOp to CastAndStoreToLdsOp for clarity - Standardize context member names (working_tile, out_tile, aux_windows) - Update README documentation with correct operation names - Clean up parameter naming in epilogue_chainer.hpp (OutWindow, AccTile, AuxWindows) - common_epilogue_ops.hpp: General-purpose ops (ScaleScalarOp, CastAndStoreToLdsOp, LoadFromLdsOp, ElementwiseOp, StoreOp, MoveWindowsOp) - cshuffle_epilogue_chainer_ops.hpp: CShuffle-specific context and slice operations - epilogue_chainer.hpp: Cleaned up parameter naming for generality - Removed test files that are no longer needed. These were added for intermediate use * update cshuffle chainer ops file w.r.t cshuffle_epilogue.hpp updates & add chainer to quant gemm example * fix compile errors - CI uses c++17 while the code had c++20 features --------- Co-authored-by: Illia Silin <98187287+illsilin@users.noreply.github.com> Co-authored-by: Adam Osewski <19374865+aosewski@users.noreply.github.com>
