OvmfPkg/VirtioFsDxe: add a scatter-gather list data type
In preparation for the variously structured FUSE request/response
exchanges that virtio-fs uses, introduce a scatter-gather list data type.
This will let us express FUSE request-response pairs flexibly.
Add a function for validating whether a (request buffer list, response
buffer list) pair is well-formed, and supported by the Virtio Filesystem
device's queue depth.
Add another function for mapping and submitting a validated pair of
scatter-gather lists to the Virtio Filesystem device.
