vsxmake: Launch console programs the same way VS does

[SirLynix]

Is your feature request related to a problem? Please describe.

When starting the executable from a vsxmake project (instead of a regular vs one), it will be run directly, and will directly close on exit, instead of leaving a console with the program output. This is useful in case of error.

Describe the solution you'd like

That running a program using a vsxmake project (using F5 or Ctrl+F5) runs it the same way VS does.

Describe alternatives you've considered

Adding a std::getchar() call to the executable, but that is intrusive and don't work with crashes.

Additional context

It seems Visual Studio use VsDebugConsole.exe internally.

Here's the process tree of a program launched from a regular VS project:

This feature seems to be related to Tools->Options->Debugging->Automatically close the console when debugging stops (has to be unchecked) in regular VS projects, and requires /subsystem:console.

Okay so this was not as complicated as I expected.

Setting the subsystem to "Console (/SUBSYSTEM:CONSOLE)" in the Visual Studio project did restore this behavior (this setting belongs to the project -> linker -> system -> subsystem).

This changes introduced an ItemDefinitionGroup in the vcxproj which sets this in the vcxproj file:

  <ItemDefinitionGroup Condition="'$(Configuration)|$(Platform)'=='debug|x64'">
    <Link>
      <SubSystem>Console</SubSystem>
    </Link>
  </ItemDefinitionGroup>

A simple way to fix this would be to do the same as vs project and generates a SubSystem entry which will be set to Console or Windows (even though xmake handles the build, this setting is used by VS to run the project).

Ok, I will look at it.

I have supported it on dev branch.

I have tested it and it works well 👍 thank you!
