OvmfPkg/VirtioFsDxe: implement the wrapper function for FUSE_WRITE
Add the VirtioFsFuseWrite() function, for sending the FUSE_WRITE command
to the Virtio Filesystem device.
(For avoiding oversized FUSE_WRITE commands, save the maximum write buffer
size that is advertized by the FUSE server, in the session init code.)
