issue: 4634244 migrate json-c from 0.13 to 0.17

[tomerdbz]

Description

Migrate the json-c library from version 0.13.1 to 0.17.0 to gain access to newer features and bug fixes. The new version uses Meson build system which is incompatible with the existing Autotools-based libxlio project.

To maintain compatibility, convert the Meson build system to Autotools:

• Create configure.ac with comprehensive feature detection for threads, atomic operations, and system headers
• Add Makefile.am with proper source file management and libtool support
• Generate pkg-config files (json-c.pc, json-c-uninstalled.pc) for proper library linking
• Add json_compat.h for backward compatibility with renamed functions

The new json-c 0.17.0 uses doca_third_party_ prefix for all exported functions to avoid symbol conflicts. Update all callers:

• src/core/config/descriptor_providers/json_descriptor_provider.cpp
• src/core/config/descriptor_providers/schema_analyzer.cpp
• src/core/config/json_object_handle.cpp
• src/core/config/json_utils.cpp
• src/core/config/loaders/json_loader.cpp
• tests/unit_tests/config/schema_analyzer.cpp

Configuration changes:

• Update configure.ac to build json-c subdirectory
• Modify config/m4/json.m4 to point to new library paths
• Update third_party/Makefile.am with proper subdirectory handling

All 94 unit tests pass. Main project builds successfully with full backward compatibility maintained.

Hi @NirWolfer, again the CI is stuck and we have many PRs like that. Its a huge problem, we are not able to merge issues and we are close to code freeze.
