Sumedh Alok Sharma e6fd5fefc4 block: Implement synchronous I/O engine for Flat VMDK
Implements synchronous I/O engine for flat VMDK backend.
It uses an extent aware worker to map each request
to one or more backing extents. The implementation supports extents
opened with O_DIRECT using AlignedFile.

Async backends of io_uring and AIO are unimplemented because
requests spanning extents cannot be submitted with one fd + offset.
