Called after `${rootfs_size}` is known, but before `${FIXED_IMAGE_SIZE}` is taken into account.

A good spot to determine `FIXED_IMAGE_SIZE` based on `rootfs_size`.

UEFISIZE can be set to 0 for no UEFI partition, or to a size in MiB to include one.

Last chance to set `USE_HOOK_FOR_PARTITION`=yes and then implement create_partition_table hook_point.
