Use wxIMPLEMENT_APP_CONSOLE() in the archive sample

Replacing wxIMPLEMENT_APP() with wxIMPLEMENT_APP_CONSOLE() allows
building the sample on Windows with CMake with wxWidgets built in
the monolithic configuration.

The archive sample is a console, not GUI, sample and console applications
should use wxIMPLEMENT_APP_CONSOLE() instead of wxIMPLEMENT_APP(). This
matters on Windows when compiling with MSVC and the linker subsystem set
to console.

It can still work when wxUSE_GUI=0 is defined but this is not possible
with wxWidgets monolithic build, where wxUSE_GUI=1 is defined for all
the projects.

Closes #26755.
