Adjust operation names of pg_aios to match the documentation

pg_aios used the terms "read" and "write" for vectored I/O read and
write operations, respectively.  The documentation refers to them as
"readv" and "writev", and the code uses internally the terms
PGAIO_OP_READV and PGAIO_OP_WRITEV for them, as of "vectored".

This commit adjusts these operation names to match with the code and the
documentation.
