Builds move to GCC 14; FS_fread warnings try to include the file path
Commits aa4090 and bda422 on main move the build toolchain to GCC 14 and try to add the file path to CWin32ReadOnlyFile::FS_fread warnings.
- aa4090: file path in FS_fread warnings; LuaJIT, Bootil, VPC and the game build with GCC 14
- bda422: ToGL builds with GCC 14 ("I pushed too soon accidentally"); fixed FreeImage not building on Windows; build scripts can now almost build on vanilla SteamRT 4
