fix: dev: Save time when creating a slab from another slab

The `dns_rdataslab_fromrdataset()` function creates a slab from an rdataset. If the source rdataset already uses a slab, then no processing is necessary; we can just copy the existing slab to a new location.

Closes #5188

Merge branch '5188-optimize-makeslab' into 'main'
