Deprecate utilities in favor of ign-utils

[chapulina]

🎉 New feature

• Closes Deprecate utilities in favor of ign-utils #171

Summary

• Added pragma messages that are printed on compilation to warn users
• Removed tests so that we don't get the messages. I wasn't sure how to suppress the message otherwise, and I think that we're fairly confident that the feature works as intended at this point.

Test it

You can restore the test and compile to see the warning, for example:

$ colcon build --cmake-args="-DBUILD_TESTING=true" --packages-select-regex=.*n-cmake
Starting >>> ignition-cmake3
--- stderr: ignition-cmake3

the #pragma messages may show up in colcon, but jenkins doesn't seem to recognize them as compiler warnings:
