cmake: Add -W options to control deprecation warnings and errors

Refactor the -Wdev and -Wno-dev to use a generic -W parser that follows
the GCC pattern.  Include support for setting CMAKE_ERROR_DEPRECATED and
CMAKE_WARN_DEPRECATED via the deprecated warning.  Add -Werror=dev and
-Wno-error=dev options so that dev warning options are in line with
deprecated warning options.  Use a new CMAKE_SUPPRESS_DEVELOPER_ERRORS
internal cache entry to store the above new dev options persistently.
Add tests for new options and updated cmake documentation and release
notes to list new options.
