core: add EXTEND_TIMEOUT_USEC={usec} - prevent timeouts in startup/runtime/shutdown...

With Type=notify services, EXTEND_TIMEOUT_USEC= messages will delay any startup/
runtime/shutdown timeouts.

A service that hasn't timed out, i.e, start time < TimeStartSec,
runtime < RuntimeMaxSec and stop time < TimeoutStopSec, may by sending
EXTEND_TIMEOUT_USEC=, allow the service to continue beyond the limit for
the execution phase (i.e TimeStartSec, RunTimeMaxSec and TimeoutStopSec).

EXTEND_TIMEOUT_USEC= must continue to be sent (in the same way as
WATCHDOG=1) within the time interval specified to continue to reprevent
the timeout from occuring.

Watchdog timeouts are also extended if a EXTEND_TIMEOUT_USEC is greater
than the remaining time on the watchdog counter.

Fixes #5868.
