Otherwise we can get situations where platform-specific opts with the same name can override each other depending on the order at which platforms are parsed, as was the case with `use_static_cpp` in Linux/Windows. Fixes #44304. This also has the added benefit that the `scons --help` output will now only include the options which are relevant for the selected (or detected) platform.
