Forward log and log level to custom bh_log callback (#3070)

Browse Source 
Follow-up on #2907. The log level is needed in the host embedder to
better integrate with the embedder's logger.

Allow the developer to customize his bh_log callback with
`cmake -DWAMR_BH_LOG=<log_callback>`,
and update sample/basic to show the usage.
