io_uring: support to inject result for NOP
Support to inject result for NOP so that we can inject failure from
userspace. It is very helpful for covering failure handling code in
io_uring core change.
With nop flags, it becomes possible to add more test features on NOP in
future.

io_uring: fail NOP if non-zero op flags is passed in
The NOP op flags should have been checked from beginning like any other
opcode, otherwise NOP may not be extended with the op flags.
Given both liburing and Rust io-uring crate always zeros SQE op flags, just
ignore users which play raw NOP uring interface without zeroing SQE, because
NOP is just for test purpose. Then we can save one NOP2 opcode.

io_uring: kill extra io_uring_types.h includes
io_uring/io_uring.h already includes io_uring_types.h, no need to
include it every time. Kill it in a bunch of places, it prepares us for
following patches.
