Introduce a new CONFIG_UORB_FORMAT Kconfig option to control whether uORB format strings are compiled in. UORB_LISTENER, UORB_GENERATOR, and DEBUG_UORB all select UORB_FORMAT automatically, so format strings are included when any of these features are enabled. This replaces the previous approach of guarding format strings with CONFIG_DEBUG_UORB, which prevented uorb_listener from displaying sensor data when debug output was disabled.

Thank you @Zepp-Hanzj :-)
- as in #3534.. we do not document this way, please update our main documentation at nuttx/Documentation as @xiaoxiang781216 noted :-)
- PR should only contain related changes, when providing documentation do not touch any other areas (i.e. uorb defines) as @linguini1 noted :-)
There are two possible locations for the iptables as with ip6tables:
- https://nuttx.apache.org/docs/latest/applications/netutils/index.html
1.1. https://nuttx.apache.org/docs/latest/applications/netutils/ip6tables/index.html <- this one needs to be created with the content you provided here.
1.2. https://nuttx.apache.org/docs/latest/applications/netutils/iptables/index.html <- this one needs an update too if you have a moment please. - https://nuttx.apache.org/docs/latest/components/net/ipfilter.html <- there is a mention of iptables here but you can reference description to the applications/netutils location when ready.
