ad163a7e25 io_uring: move a few private types to local headers
Commit 3a3d47fa9cfd ("io_uring: make io_uring_types.h public") moved
a bunch of io_uring types to a kernel wide header, so we could make
tracing a bit saner rather than pass in a ton of arguments.

However, there are a few types in there that are not really needed to
be system wide. Move the cancel data and mapped buffers back to the
appropriate io_uring local headers.

27a9d66fec 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.

e6f89be614 io_uring: introduce a struct for hash table
Instead of passing around a pointer to hash buckets, add a bit of type
safety and wrap it into a structure.

38513c464d io_uring: switch cancel_hash to use per entry spinlock
Add a new io_hash_bucket structure so that each bucket in cancel_hash
has separate spinlock. Use per entry lock for cancel_hash, this removes
some completion lock invocation and remove contension between different
cancel_hash entries.

a4ad4f748e 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.
