This also keeps the functionality of hrev53848, which simplifies the
list of disks searched for bootable partitions; however, it maintains
the previous behaviour of platform_get_boot_partitions that continues
to iterate over a list of possible boot partitions, which should
allow finding a bootable BFS partition better in more circumstances.
Particularly, there are numerous reports of the UEFI loader entering
the boot menu despite it finding a bootable partition, which this
should address.
EFI's device_contains_partition is also structured such that it
compares the disk GPT table of the partition the loader is
querying of the EFI disk's GPT table, in the case that there are
multiple disks, as the most reliable method of comparison, with
a generic fallback for non-GPT disks, which will be less reliable.
This reverts commit 0d932a49ad.
