Create a separate file listing backend types
Use our established coding pattern to reduce maintenance pain when
adding other per-process-type characteristics.
Like PG_KEYWORD, PG_CMDTAG, PG_RMGR.
To keep the strings translatable, the relevant makefile now also scans
src/include for this specific file. I didn't want to have it scan all
.h files, as then gettext would have to scan all header files. I didn't
find any way to affect the meson behavior in this respect though.
