Since commit 06d9e67f (FindPython: Add capability to specify directly
artifacts, 2019-08-15, v3.16.0-rc1~157^2) we accidentally add the result
variables `Python*_LIBRARY_RELEASE` and `Python*_LIBRARY_DEBUG` to the
cache.  They are always computed from other results and so should not be
presented to users in cmake-gui and ccmake to edit.

Issue: #20362
