cmScanDepFormat: Drop unused "outputs", "inputs", and "depends" fields

These fields are specified by our `P1689r3` paper, but are not actually
needed.  The dependencies of the scanning results themselves can be
captured via normal depfile logic.  Avoid saving this possibly-large
information in the scanning results.  It is not needed by later steps.
