Swap order of extern/static and pg_nodiscard
When pg_nodiscard was first added, the C standard draft had it as a
function specifier, and so the code comment about placement was
written with that in mind. The final C23 standard has it as an
attribute and the placement rules are a bit different for that.
Specifically, it needs to be before extern or static. (Or at least
both current clang and gcc require that.) So just swap these. (To be
clear: The current implementation with gcc attributes doesn't care.
This change is just for maximum forward compatibility for non-gcc
compilers.) This also keeps the order consistent with the previously
introduced pg_noreturn. Also update the code comment to reflect the
mentioned developments since its introduction.
