Declare json in OrcaSlicer.cpp on Every Platform

OrcaSlicer.cpp had its "using namespace nlohmann;" and the json include
inside the Linux-only include block, so on Windows and macOS it took
json from AppConfig.hpp's global directive, which is gone. The include
and a "using json = nlohmann::json;" now sit outside the block.
