fixed platforms lookup / set proper platform type for unix32-unsigned and unix64-unsigned / copy platforms in CMake

[firewave]

Extracted from #4325.

This is the first step in getting rid of hard-coded platforms and should have no effect at all beside making it consistent (and uncovering issues).

We should not output any important information with std::cout directly. Is it just for debugging? It will not be shown properly in the GUI.

[firewave]

It's verbose information. I just checked other code and that uses the ErrorLogger::reportOut(). Will adjust.

[firewave]

Turns out that is not the function to use since it is not available at that point.

Also the rest of the code is not doing this consistently either. So I propose to apply these changes as is. With a later PR I will refactor out the explicit std::cout and std::cerr usage as a whole.

[firewave]

Can this be merged? It blocks further improvements.

I baffled as the CI is fine. Maybe the platform files were not properly copied on your system.

Apparently, the test is executed in the test subdirectory when using the default setting for Working Directory = $(ProjectDir).
The tests pass when adding filenames.push_back("../platforms/" + filename + ".xml");
