fix: dev: Standardize CHECK and RETERR macros

Previously, there were over 40 separate definitions of `CHECK` macros, of
which most used `goto cleanup`, and the rest `goto failure` or `goto out`.
There were another 10 definitions of `RETERR`, of which most were identical
to `CHECK`, but some simply returned a result code instead
of jumping to a cleanup label.

This has now been standardized throughout the code base: `RETERR` is for
returning an error code in the case of an error, and `CHECK` is for jumping
to a cleanup tag, which is now always called `cleanup`. Both macros are
defined in `isc/util.h`.
