debug: move "nonexistent config path" message to much higher verbosity level (#34201)
We currently report that searched config paths don't exist at debug level 1, which
clutters the output quite a bit:
```console

It is very rare that I want to know this much information about config search, so I've
moved this to level 3. Now at level 1, we can see much more clearly what configs were
actually found:
```console
> spack -d solve --fresh --show asp hdf5 > hdf5.lp
==> [2022-11-29-14:19:04.035457] Imported solve from built-in commands
==> [2022-11-29-14:19:04.035818] Imported solve from built-in commands

```
You can still get the old messages with `spack -ddd` (to activate debug level 3).
