Getting correct Visual Studio 2022 for OCaml 5.3+

[dra27]

The MSVC port of OCaml will be restored in OCaml 5.3, but it requires Visual Studio 2022 or later. The error messages at present are clear about the problem (old Visual Studio) but not so clear about the fixes.

Cross-referencing:

• Discuss thread on the problem
• Clearer status information from opam package as to which Visual Studio was selected metastack/msvs-tools#19
• Wiki documentation for required Visual Studio packages metastack/msvs-tools#20
• Ability to execute msvs-detect within opam switches metastack/msvs-tools#21

https://github.com/diskuv/dkml-runtime-distribution/blob/main/src/windows/Machine/Machine.psm1 has logic to detect and suggest what needs to be installed. (I read it from bottom to top)
