Move both the opcodes related to it, and the internals code dealing with
it.

io_uring: move cancelation into its own file

This also helps cleanup the io_uring.h cancel parts, as we can make
things static in the cancel.c file, mostly.

io_uring: move poll handling into its own file

Add a io_poll_issue() rather than export the general task_work locking
and io_issue_sqe(), and put the io_op_defs definition and structure into
a separate header file so that poll can use it.

io_uring: move fdinfo helpers to its own file

This also means moving a bit more of the fixed file handling to the
filetable side, which makes sense separately too.

io_uring: move epoll handler to its own file

Would be nice to sort out Kconfig for this and don't even compile
epoll.c if we don't have epoll configured.

io_uring: move to separate directory

In preparation for splitting io_uring up a bit, move it into its own
top level directory. It didn't really belong in fs/ anyway, as it's
not a file system only API.

This adds io_uring/ and moves the core files in there, and updates the
MAINTAINERS file for the new location.
