feat(triton): add JIT backend with add operator

[fuyou4546]

Summary

• Triton JIT backend with kernel caching and autotune
• Add operator JIT implementation (implementation_index=7) via src/triton/ops/add/jit.h
• scripts/generate_wrappers.py, detects ops using config_t and emits config parameter with inline config-dict parsing
• src/CMakeLists.txt, compiles JIT infra (jit.cc / compiler.cc) and links pybind11::embed
• src/config.h, Config::set_extension / extension() for attaching opaque extension data

Motivation

Support JIT compilation for Triton operators. Kernel caching, config passing, and autotune orchestration are implemented in C++. The compilation step bridges to triton.compile via pybind11::embed.

Closes N/A

Type of Change

• feat — new feature / new operator / new platform
• fix — bug fix
• perf — performance improvement (no behavioral change)
• refactor — code restructuring without behavior change
• test — adding or fixing tests only
• docs — documentation only
• build / ci — build system or CI configuration
• chore — tooling, formatting, or other non-code changes
• Breaking change (requires a ! in the Conventional Commits prefix or a BREAKING CHANGE: footer)

Notes for Reviewers

• This PR builds on the AOT backend commits in feat/triton-backend and depends on them being merged first.
• generate_wrappers.py has additions: _uses_config_extension for detecting ops with config_t, _generate_triton_jit_config_parser for emitting inline config-dict parsing, and conditional uses_config path in _generate_call.
• Config class (src/config.h) now has a std::shared_ptr<Config> extension_ member with set_extension / extension accessors, used to pass compile configurations from Python bindings to operator implementations.
• Config dict parsing is emitted inline in the generated binding header.

代码需要遵循 CONTRIBUTING.md，其中 C++ 主要是遵循 Google C++ Style Guide。目前的 naming 之类的好像没有 follow 这些 convention，需要修改一下。
