Updated cmdLine from 0.120.0 to 0.121.0 and PG GUI from 0.114.0 to 0.115.0

scripts/test_cmdline_args.sh <projectGenerator> <OF root> [platform] - 34 cases run from the macOS, Linux and Windows CI (scripts/*/test_cmdline.sh), so a value taken as the project path (#693) fails CI instead of generating a project somewhere else. After every case it checks that nothing new appeared at the OF root, in apps/ or apps/myApps/.

• project path: attached / = / separate values, short and long, relative and absolute -o, every value option separated (-a -D -P -s), path only, missing path, bare value option at the end, two paths, option after the path, the OF folder as the project, unknown platform, unknown option, --platform typo, bad -o, --dryrun writes nothing, -r folder
• system frameworks / libs (System frameworks / libraries for macOS, iOS, tvOS kept in config.make, GUI fields and help tab #690): commas, comma+space, spaces only, .framework suffix, duplicates, libX.tbd / -lX / libX / X, libs given to -f, kept on update, empty -f / --system-libs= remove them, += lines in config.make, Xcode file refs
• defines / app version / build / emscripten wasm (platforms with a config.make): values written, bad values warn and keep the project's

Found while writing them, fixed here:

• an unknown platform crashed (-p bogus -> exit 139, getTargetProject returned no project); now Unknown platform, exit 64
• on Windows (MSVC) no -p crashed the same way: the host platform checked __WIN32__, which MSVC doesn't define, so it was empty; now _WIN32 too, so it's vs again
• unknown options were ignored (--bogus -> exit 0); now Unknown option, exit 64
• -p osx with no project path made a project called osx; a bare value option at the end now takes the value (missing project path, exit 64). Only -f / --frameworks / --system-libs keep meaning empty there
• --platform osx (typo of --platforms) was the long name of -i: printed the host platform and exited 0 without touching the project. Renamed to --getplatform, as --help already said
• osx Test 2 passed two paths (../../examples/ ./projectGenerator) and the osx tests didn't check exit codes, so after Fix cmdLine placing projects into oF root with certain params  #693 it failed without failing CI

Run locally on macOS for osx / linux64 / vs, with the binary inside and outside an OF tree: 34 / 34 / 30 cases (vs has no config.make template, so no defines / version cases), 0 failures. Against the binary from before #693: 54 failures; against current master: the 4 fixed here.

Merged as part of #695 (3afaff3): #695 was stacked on this branch and its squash merge brought these commits into master, so rebased onto master this PR is empty. On master: scripts/test_cmdline_args.sh run from the macOS / Linux / Windows CI, unknown options / platforms are errors instead of being ignored / crashing, a bare value option at the end, --getplatform, the Windows host platform fix, and Updated cmdLine from 0.120.0 to 0.121.0.
