Add sanity check to executable CD + more (#3190)

Building executables without any testing is quite sketchy, let's at
least verify they won't crash on startup and format Black's own
codebase.

Also replaced "binaries" with "executables" since it's clearer and
won't be confused with mypyc.

Finally, I added colorama so all Windows users can get colour.
