I take this of from the CI queue now and let this wait for #18162 - once this is in it can use fmt when used anyway as before. Especially for newlib users there is quite a bit of memory to be safed when not using printf. |

Also use `IS_USED(MODULE_FMT)` rather than the preprocessor and rely on the optimizer to eliminate the dead branch.
- add `netif_get_ipv6()` to query IPv6 (as a slim convenience wrapper for `netif_get_opt()`) - add `netifs_get_ipv6()` to query IPv6 addresses of all netifs - add `netif_print_ipv6()` to print the IPv6 address(es) of a single netif - add `netifs_print_ipv6()` to print the IPv6 address(es) of all netifs

The address output of `examples/nanocoap_server` was changed to JSON in RIOT-OS/RIOT#18161. This changes the parsing to account for that.

Contribution description
At a few places this was already either done by hand or via an ugly hack to call the shell handler if
ifconfigfrom C, so apparently there is a use for it. In addition, the hack of calling a single shell handler doesn't work well with XFA, as XFA items are not subject to link time garbage collection.Testing procedure
Run
examples/gnrc_minimaland it should still print all IPv6 address (but now as JSON, because that's what cool kids do now).Issues/PRs references
Needed for #18152
