nuttxs 7b3913da60 libs/libc/netdb: Optimize the timeout calculation logic: ...

1. Adopt an exponential backoff strategy () to dynamically adjust the timeout
   duration, which is suitable for retry scenarios.
2. Optimize the default configuration to set the initial timeout to 5 seconds.
3. Support dynamic modification of the maximum timeout limit to adapt
   to different scenarios.
Reference: RFC 1536 (section on retransmission implementation recommendations)
