[block] Allow for additional SAN boot parameters alongside filename

The drive specification alone does not necessarily contain enough
information to perform a SAN boot (or local disk boot) under UEFI.  If
the next-stage bootloader is installed in the EFI system partition
under a non-standard name (e.g. "\EFI\debian\grubx64.efi") then this
explicit boot filename must also be specified.

Generalise this concept to use a "SAN boot configuration parameters"
structure (currently containing only the optional explicit boot
filename), to allow for easy expansion to provide other parameters
such as the partition UUID or volume label.
