Run to-python3.sh on Trilinos CMake files (TriBITSPub/TriBITS#610)

This is the result of running the script:

   cmake/tribits/refactoring/to-python3.sh

on the entire Trilinos source tree.

This just changes from "PYTHON_EXECUTABLE" to "Python3_EXECUTABLE".

NOTE: The script also fixes up then carriage-return/line-feed chars (which is
why all of the lines of the file packages/compadre/CMakeLists.txt was
changed).
