Merge branch 'LTS-C++17'

[morousg]

• LTS-C++17: (157 commits) Made all values that reside in registers, to be passed as const value, instead of const reference, to be more consistent with the reality of the variables and values. If nvcc where very strict, or there where no inlining in one function, it would trigger local memory usage. Simplified get wrapper and get_opt implementations Making get_opt generic like get Added missing include and fixing comment typos Removed unnecessary cast Using correct macro in OpenType Instantiable Operation further simplifying operation_types file Removing unnecesary code and adapting some benchmarks to new Point aggregate Making make and cat for OperationTuple host only functions. They should be used only on CPU. Fixing comments and removing unnecesary decltype(auto) Making OperationTuple an aggregate Removing unnecessary decltype(auto) Making some changes to avoid confusion with the two types of operator| in InstantiableOperations Added operator[] implementations with index passed as size_t Removing unnecesary decltype(auto), and adding a comment. Reducing function call depth in all operations exec and build functions, by moving their definition to the macros. Fixing bugs in memory operations Removing unnecesary decltyp(auto) Cleaning unnecessary decltype(auto) usage Revert .gitignore changes - remove CodeQL entries ...

Pull request overview

This PR merges the LTS-C++17 branch, bringing a broad refactor of the fused-kernel execution/operation model APIs (notably operation typing, tuple storage/access, and fusion/execution plumbing), plus corresponding updates across unit tests, examples, and benchmarks.

Changes:

• Refactors operation typing and fusion APIs (e.g., opIs<>, new OperationTuple storage/access via get_opt, updated fusers/executors).
• Shifts many operation exec() signatures from const T& to T (by-value) for register-resident values and consistency across CPU/CUDA compilation.
• Updates tests/examples/benchmarks to the new APIs and data structures; adds a few new test/example files.
