Use the crates.io implementation of tempfile instead of our own version.
Our reimplementation is kept in the tree for now in case of dependencies
outside of the crosvm tree; it can be removed later once those are fully

This CL makes the following fundamental changes to cros_async:
1. Removes PollOrRing and replaces it with IoSourceExt, and the
subtraits ReadAsync & WriteAsync. The blanket implementation of
IoSourceExt has been dropped, and replaced with source specific
implementations of the trait. Those implementations are where
the code from PollOrRing has been moved.
2. Pinning for IoSource has been dropped from UringSource & the uring
futures. This appears to be safe because the IoSource doesn't contain
any self refs, or perform any operations beyond forwarding to the
RegisteredSource. (The FD is duped before being passed to
RingWakerState by RegisteredSource, so there doesn't seem to be any
data which would require pinning.)
3. U64Source was replaced by EventAsync.
It also switches all Error enums to use thiserror, which reduces
boilerplate.

For now, this crate simply re-exports all of sys_util, but it will
be updated to provide new interfaces when needed. This is the
first step to making crosvm not directly depend on sys_util, so
that we can make the interface changes we need without fear of
negatively affecting (i.e. completely breaking) other usages
within chromeos.

This adds a new disk file type next to raw files and qcow images that
represent an indirection to further raw disk files. The disk file
itself is a proto file with references to file paths for other disks to
open and their virtual offsets and lengths.
The intention is to make it easy to assemble a single virtual hard disk
out of several distinct partition files. In the particular case of
Cuttlefish running Android in a VM, this is relevant as the Android
build system distributes partitions as separate raw files. While the
simple solution is to pass each partition as a separate raw disk, some
functionality (like the bootloader) assumes there is a partition table
with multiple distinct partitions on a single disk.
Implementing composite disk support in the VMM bridges this gap through
supporting the general-purpose case of a disk built out of multiple
component files.
If desired, this can be extended to support qcow files to support
unusual configurations like a mixed qcow/raw disk.
Enabled with the "composite-disk" feature.
