Make assert_refcount skip the OBJECT REFCOUNT check with needs:debug tag (#11487)

This PR add `assert_refcount_morethan`, and modify `assert_refcount` to skip
the `OBJECT REFCOUNT` check with `needs:debug` flag. Use them to modify all
`OBJECT REFCOUNT` calls and also update the tests/README to be more specific.

The reasoning is that some of these tests could be testing something important,
and along the way also add a check for the refcount, and it could be a shame to skip
the whole test just because the refcount functionality is missing or blocked.
but much like the fact that some redis variants may not support DEBUG,
and still we want to run the majority of the test for coverage, and just skip the digest match.
