[wix-devs] Visual Studio Extension add support to detect 2022 (#6727)

[Christopher Painter]

 For issue https://github.com/wixtoolset/issues/issues/6727

I submitted PR 542 https://github.com/wixtoolset/wix3/pull/542


The approach is to simply extend everything done for VS2019 to cover VS2022.  On the C++ side,   copy paste the 2019 bits and rename them 2022 and change VS ver from 16 to 17.   On the wixlib side clone all the 2019 fragments and rename to 2022.

The only thing of note is that <2019 are 32bit installs and 2022 is 64bit install.   So perhaps a doco update could be made to remind people of the bitness design constraints of MSI.

Come to think of it, the doco would need to be updated to mention the 2022 projects.   I'm guessing that would be it's own issue?

Feedback?
