Matthew Woehlke 597c573d7d if: Add DIAGNOSTIC <category> condition

Add an existence check to the `if` command for diagnostic categories,
mirroring the check for policies. Aside from being desirable for
consistency's sake, this will make it easier for users to write logic to
manipulate diagnostics from newer versions of CMake that don't exist
today.
