Add LSN location in some error messages related to WAL pages
The error messages reported during any failures while reading or
validating the header of a WAL currently includes only the offset of the
page but not the compiled LSN referring to the page, requiring an extra
step to compile it if looking at the surroundings with pg_waldump or
similar. Adding this information costs a bit in translation, but also
eases debugging.
