Subject: pgsql: aio: Add errcontext for processing I/Os for another backend

aio: Add errcontext for processing I/Os for another backend
Push an ErrorContextCallback adding additional detail about the process
performing the I/O and the owner of the I/O when those are not the same.
For io_method worker, this adds context specifying which process owns
the I/O that the I/O worker is processing.
For io_method io_uring, this adds context only when a backend is
*completing* I/O for another backend. It specifies the pid of the owning
process.
