[radio-spinel] add log on RCP timeout error during init (#9059)

Browse Source 
This commit adds new logs to `HandleRcpTimeout()` when an RCP timeout
occurs during initialization. This error is often incorrectly
reported as a bug, but it is usually caused by an incorrect
configuration or a bad RCP image. The new logs aim to provide
information and hints to the user about the cause of the error.
