test: More cleanup of Windows targets in the module test matrix

It's kind of unclear what `*-windows-none` actually means, but as far as LLVM is
concerned, it's equivalent to `*-windows-msvc`. For clarity, only test
`*-windows-msvc` and `*-windows-gnu`. #20690 will clean this situation up
eventually.

Also ensure coverage of `link_libc = true` and `link_libc = false` for both.
