Revert topic 'cmake-W-options' (#15747)

The changes in commit c96fe0b4 (cmake: Add -W options to control
deprecation warnings and errors, 2015-07-28) fail to account for
-Wdev warnings produced by places in CMake other than message().
This causes a regression in which -Wno-dev fails to suppress such
warnings.  Revert the feature until it can be revised accordingly.
