Fix and test stdlib JLL deps on Windows

[IanButterworth]

• Extends testing added in Convert remaining JLL stdlibs to LazyLibraries #58444 to Windows
• Uses ObjectFile.jl instead of relying on system libs being installed
• Reworks the JLLs to be a bit easier to work with, and not have global internal objects

This is shipped with Visual Studio IIRC, so unlikely to be on the CI machines

I wonder if we have to use ObjectFile.jl instead? I'm not aware of any other open-source / freely-distributed utility to print this on Windows, but maybe @staticfloat knows of something

I don't know how easy it is for us to install ObjectFile during base tests, that's why I punted on this and just used CLI tools when available. I usually use readelf cross-compiled for Windows to do this kind of dumping, but of course that's not available on the tester images, only the builder images. We could download, for instance, this archive and use the readelf within it to dump the dependencies perhaps.

Note that readelf is also missing on some of the linux runners.

We have llvm-tools, which include readobj/readelf that can parse the info llvm-readelf --coff-imports with that artifact, which means you can also get there from libLLVM's COFFObjectFile (though it doesn't look like you can get there from the C API)

[IanButterworth]

I believe llvm-tools requires running a make install which hasn't been run on these runners? I'm trying ObjectFile.jl, which works on macOS
