Windows VC14.20 project missing

[dsv123]

Windows projects included VC14, VC14.10, VC14.30 but not VC14.20.
OpenSSL and WolfSSL bat scripts mention VC14.20 so I don't suspect an underlying problem with this platform toolset.

Updated the templates to produce a VC14.20 project. Project opens (and builds) in Visual Studio 2019 as expected.
The VC14.30 solution contained text "Visual Studio 15" instead of "Visual Studio 17", updated.

Since Visual Studio 2012 and older all seem to be end of life now, I think we can drop them from the release archives. Based on this: https://learn.microsoft.com/en-us/visualstudio/releases/2019/servicing-vs2019

Thanks!

@dsv123 this does not add any code to Makefile.am in the style of 14_30 so I'm pretty sure this then does not create working 14.20 files in the tarballs. See:

curl/Makefile.am

I realized this when I made #12288 just now

Anyway, that should be fixed in a separate PR, just wanted to highlight this.
