Fix GreenGrass Discovery demo failure in Nuvoton Ethernet board (#2242)…

… (#2249)

* Fix mapping of configPRINTF to vLoggingPrintf to fix message mangling

* Fix incorrect mapping of FreeRTOS_debug_printf

* Fix incorrect mapping of FreeRTOS_debug_printf for aws_tests

* Enable ipconfigINCLUDE_FULL_INET_ADDR for Nuvoton Ethernet GreenGrass demo

* Add logs GGD_SecureConnect_Connect for improving debuggability

* Hygiene improvements

* Add error log for SOCKETS_GetHostByName failure

* Increase logging message length in aws_demo config to avoid truncated message causing CI failure in
