Andres Freund ef64fe26ba aio: Add WARNING result status 
If an IO succeeds, but issues a warning, e.g. due to a page verification
failure with zero_damaged_pages, we want to issue that warning in the context
of the issuer of the IO, not the process that executes the completion (always
the case for worker).

It's already possible for a completion callback to report a custom error
message, we just didn't have a result status that allowed a user of AIO to
know that a warning should be emitted even though the IO request succeeded.

All that's needed for that is a dedicated PGAIO_RS_ value.

Previously there were not enough bits in PgAioResult.id for the new
value. Increase. While at that, add defines for the amount of bits and static
asserts to check that the widths are appropriate.
