This removes a dependency of 'core' on 'contrib'.
Backport of 83ba0a9 from master.
This deprecation occurs after the alpha, but it's a prerequisite
for fixing decently #18194 which is a release blocker.
They are now called "makemessages", "compilemessages" and "cleanup". This is
backwards incompatible for make-messages.py and compile-messages.py, although
the old executables still exist for now and print an error pointing the caller
to the right command to call.
This reduces the number of binaries and man pages Django needs to install.
Patch from Janis Leidel.
