Update qet_compilation_vars.cmake

The comments describing the terminal_names layout were inherited from a
previous version and no longer matched the actual assignment order:

    terminal_names << nc_name << no_name << common_name;
    i.e. [0]=NC, [1]=NO, [2]=Common

Update all affected comments to reflect the current storage order.
