tree-wide: add SD_ID128_MAKE_STR, remove LOG_MESSAGE_ID

Embedding sd_id128_t's in constant strings was rather cumbersome. We had
SD_ID128_CONST_STR which returned a const char[], but it had two problems:
- it wasn't possible to statically concatanate this array with a normal string
- gcc wasn't really able to optimize this, and generated code to perform the
  "conversion" at runtime.
Because of this, even our own code in coredumpctl wasn't using
SD_ID128_CONST_STR.

Add a new macro to generate a constant string: SD_ID128_MAKE_STR.
It is not as elegant as SD_ID128_CONST_STR, because it requires a repetition
of the numbers, but in practice it is more convenient to use, and allows gcc
to generate smarter code:

$ size .libs/systemd{,-logind,-journald}{.old,}
   text	   data	    bss	    dec	    hex	filename
1265204	 149564	   4808	1419576	 15a938	.libs/systemd.old
1260268	 149564	   4808	1414640	 1595f0	.libs/systemd
 246805	  13852	    209	 260866	  3fb02	.libs/systemd-logind.old
 240973	  13852	    209	 255034	  3e43a	.libs/systemd-logind
 146839	   4984	     34	 151857	  25131	.libs/systemd-journald.old
 146391	   4984	     34	 151409	  24f71	.libs/systemd-journald

It is also much easier to check if a certain binary uses a certain MESSAGE_ID:

$ strings .libs/systemd.old|grep MESSAGE_ID
MESSAGE_ID=%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x
MESSAGE_ID=%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x
