24c8cce012 block_util: Add synchronous support for fixed VHD disk files
Relying on the simplified version of the synchronous support for RAW

introduces the synchronous support for fixed VHD disk files.

With this patch, the fixed VHD support is complete as it is implemented
in both synchronous and asynchronous versions.

b2e5dbaecb block_util, vmm: Add fixed VHD asynchronous implementation
This commit adds the asynchronous support for fixed VHD disk files.

It introduces FixedVhd as a new ImageType, moving the image type
detection to the block_util crate (instead of qcow crate).

It creates a new vhd module in the block_util crate in order to handle
VHD footer, following the VHD specification.

It creates a new fixed_vhd_async module in the block_util crate to
implement the asynchronous version of fixed VHD disk file. It relies on
io_uring.

b8bbe244b7 block_util: Ensure all io_uring operations are asynchronous
Some operations complete directly after they have been submitted, which
means they are not submitted asynchronously and therefore they don't
generate any ioevent. This is the reason why we are not processing some
of the completed operations, which leads to some unpredictable
behaviors.

Forcing all io_uring operations submitted to the SQE to be asynchronous
helps simplifying the code as it ensures the completion of every
operation will generate an ioevent, therefore no operation is missed.

c03dbe8cc7 virtio-devices: block: Support multiple data descriptors
The Windows virtio block driver puts multiple data descriptors between

over the descriptor chain until the end is reached accumulating the
address and length pairs in a vector. For execution iterate over the
vector and make sequential reads from the disk for each data descriptor.
