fix: Resolve compilation issues with fmt library and formatters

Fix multiple compilation errors preventing successful build:

* Add const qualifier to custom fmt formatter functions across codebase
  - Updated formatters in logging, shader recompiler, texture cache, and other modules
  - Ensures compatibility with newer fmt library versions

* Add missing fmt/ranges.h includes for fmt::join usage
  - Fixed fmt::join calls in Vulkan renderer, GDB stub, NFC service, and main window
  - Resolves "no member named 'join' in namespace 'fmt'" errors

* Exclude unsupported platforms from Boost.Process usage in debugger
  - Extended conditional compilation to avoid Boost.Process where unavailable

* Fix type casting issues in AOC service manager
  - Resolved std::min type mismatch with explicit casting
