Yashvardhan Agarwal 15e81397a4 [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
