find_package: Test error and warning messages in failure cases 

Add a "CMakeCommands.find_package" test to run CMake on a bunch of cases
in which find_package fails.  Check that the process return code and
warning/error messages are as expected.  Record expected test output in
corresponding files for reference by the check.  These files will also
serve as a reference for the message text in each case.
