IoBuf is defined in a platform-specific way (it is either iovec on unix
or WSABUF for windows), so it fits into the mission statement of the
base crate, which is meant to be *the* platform abstraction layer in
crosvm.
IoBufMut and VolatileMemory/VolatileSlice are defined in terms of IoBuf,
so they are also moved into base for consistency. Every crate that uses
these types already depended on base, so no extra dependencies are
added, and a few can be removed.

io_uring allows you to submit a lot of file operations. Those operations
have corresponding syscalls, but bypass the seccomp filter since they
are submitted by single syscall. To address this security hole, the
IORING_REGISTER_RESTRICTIONS can be used to apply an allow-list of
operations to a given io_uring queue.
This commit introduces `IORING_REGISTER_RESTRICTIONS` support for
`URingContext`, and has URingExecutor apply a basic allow-list to the
UringContexts that it creates. This basic allow-list is limited to
operations allowed by common_device.policy plus fsync and fallocate.
However, note that this commit is only one step for the effective jail
of io_uring. Since `IORING_REGISTER_RESTRICTIONS` is applicable only
per-queue, a compromised device process can still easily bypass this
restriction just by creating another io_uring queue. The effective jail
is completed with coming changes that allow executor creation only
before jailing.
This commit also updates the policy file with `io_uring_register`.

The `ReadAsync` and `WriteAsync` traits accept file offsets as an
`Option<u64>`. The epoll executor interprets `None` as "current file
position" and the io_uring executor interprets `None` as position zero.
This change updates the io_uring executor in favor of the epoll executor
behavior.
It is important to differentiate between position zero and "current file
position" when you don't know whether a file is seekable. For example,
console and serial devices should support both types of files as input.
