CTest: Rename PROCESSES test property to RESOURCE_GROUPS

The `PROCESSES` test property name added for CMake 3.16 is too close to
the existing `PROCESSORS` test property.  Furthermore, the property in
principle specifies groups of resources organized in a way that is
meaningful to a particular test.  The groups may often correspond to
processes but they could have other meanings.  Since the property name
`PROCESSES` has not been in a final 3.16 release yet, simply rename it
to `RESOURCE_GROUPS`.

Fixes: #19914
