Add user custom timestamp interface

Two new macros are introduced so that users can use their customized
timestamps for DLT messages:
- DLT_LOG_TS(CONTEXT, LOGLEVEL, TS, ARGS ...)
- DLT_LOG_ID_TS(CONTEXT, LOGLEVEL, MSGID, TS, ARGS ...)
Detailed explanations can be found in dlt_for_developers.md.

Also a new option is added to dlt-system to use events' timestamps
from journald adapter.
