catalog: add more entries

While message IDs are about more than catalog entries (they make
messages recognizable), I think it makes sense to document at least all
those messages that indicate problems with catalog entries, in an
attempt to be helpful to users.

 Clearing the TPM has the effect of invalidating all keys locked to the TPM,
 including full disk encryption keys. Because of that care should be taken that
 access to relevant resources is retained via other means.

+Process @COREDUMP_PID@ (@COREDUMP_COMM@) terminated abnormally and generated a
+stack trace.
+
+This usually indicates a programming error in the crashing program and should
+be reported to its vendor as a bug. A program stack trace is available that

+
+One or more processes in the @UNIT@ unit have been killed by systemd-oomd, in
+order to counter an out-of-memory situation on the system. This usually
+indicates that the system is low on memory and systemd-oomd decided to
+terminate one or more processes to reduce memory pressure.

+Note that the memory pressure might or might not have been caused by @UNIT@.

+
+A kernel device @DEVICE@ has been encountered whose identification cannot be
+turned into a valid systemd unit name. This typically indicates a problematic
+device hierarchy (i.e. too deep nesting of buses) or drivers.
+
+For devices like this no .device unit will be created that follows the
+underlying kernel device's state, and hence no dependencies on such a unit can
+be fulfilled.

+If watchdog support is configured, but the watchdog hardware cannot be opened
