Introduce new build configuration "64bit-no-nan-tagging" for both 64-bit and 32-bit platforms, defining WREN_NAN_TAGGING=0 to disable NaN tagging in the Wren CLI. Update Makefiles, premake5.lua, and Visual Studio solution/project files to support the new config with appropriate compiler flags, linker settings, and platform-specific defines (e.g., _GNU_SOURCE on Linux, _DARWIN_* on macOS).
Add new projects/vs2017 directory containing wren-cli.sln solution file,
wren_cli.vcxproj project file with Debug/Release 32/64-bit configurations,
and wren_cli.vcxproj.filters file organizing source files into deps/libuv,
deps/wren, and src filter categories for the VS2017 build system.
