Currently we have the following .vsxproj files:

• antlr4cpp-vs2013.vcxproj
• antlr4cpp-vs2015.vcxproj
• antlr4cpp-vs2017.vcxproj
• antlr4cpp-vs2019.vcxproj

I suggest removing the first three and adding antlr4cpp-vs2022.vcxproj:

• antlr4cpp-vs2019.vcxproj
• antlr4cpp-vs2022.vcxproj

@mike-lischke what do you think?

Also, these projects can't be built because they weren't updated after some files removing (for instance, ATNSerializer.cpp).
