[platform] implement otPlatLogOutput platform API (#12762)

Browse Source 
This commit provides the platform-level implementation for the
instance-aware logging API `otPlatLogOutput()`. This API is used when
`OPENTHREAD_CONFIG_LOG_INSTANCE_AWARE_API_ENABLE` is enabled, allowing
the platform to receive the `otInstance` pointer with each log line.

The new API is implemented across:
- The simulation platform logging.
- The POSIX platform using `syslog()`.
- The NCP base to route logs to the NCP host.
- The CLI logging module.
- Unit tests and mock platforms.

The `OPENTHREAD_CONFIG_LOG_INSTANCE_AWARE_API_ENABLE` configuration is
also enabled for Toranj simulations to support multi-instance log
testing.
