This pull request introduces a comprehensive new API interface for the blockchain, leveraging OpenAPI v3 to facilitate direct consumption of chain data by GUI and web applications. This change significantly refines the project's build infrastructure, incorporating Conan for dependency management and CMake for configuration, alongside the integration of an OpenAPI Generator to produce SDKs for multiple languages.
### Highlights
* **New API Interface**: Introduced a new API interface using OpenAPI v3 to enable GUI/WEB development to consume chain data without needing custom server applications.
* **Build System Enhancements**: Significant updates to the build system, including Makefile, CMake, and Conan configurations, to streamline the build process and support new functionalities.
* **Multi-language SDK Generation**: Integrated OpenAPI Generator to automatically create SDKs for various programming languages, including Go, Angular, and PHP, simplifying client-side integration.
Updated CMakePresets.json to add 'testnet' and 'mainnet' workflows, removed unused Windows preset, and improved environment and cache variable handling. Makefile targets for testnet and mainnet workflows were added, and Conan-related targets were renamed for consistency. Added a function to reset ConanPresets.json in CleanBuild.cmake and fixed the path for GetConan.cmake in conan_provider.cmake. Deleted obsolete .idea/cmake.xml.
* Add CMake and Conan presets, update build config
Introduces CMakePresets.json and ConanPresets.json for standardized build configuration. Updates Makefile to use CMake presets, modifies .gitignore for IDE files, and refines conanfile.py to support CI option and preset integration.
* Update Makefile
* Update _on-pr.yml
* Refactor build presets and folder layout for Windows
Updated Makefile and GitHub workflow to use configurable build and configure presets, improving flexibility for different environments. Adjusted CMakePresets.json to fix preset naming and version, and refactored conanfile.py to set build folders based on compiler type, ensuring correct folder structure for MSVC and other compilers.
* Update build presets and CPack config for Windows
Set PRESET_CONFIGURE to 'conan-default' for Windows builds in Makefile and GitHub workflow. Broaden CPack packaging conditions to include additional build types and comment out WIX generator settings for Windows in CPackConfig.cmake.
Added .idea configuration files for JetBrains IDE support and updated .gitignore to exclude only specific userland .idea files. Refactored CMakeLists.txt to improve include_directories usage, re-enable -fno-fat-lto-objects for GNU compilers. This improves IDE integration and build configuration clarity.
