fastbootd: Add an update-super command to sync the super partition.
This change introduces an "update-super" command to the fastboot
protocol. Unlike the "flash" command, which copies raw or sparse data to
a partition, the "update-super" command requires the data to be a super
image generated by lpmake.
If the super partition is not yet formatted (or is corrupt), then it
will be formatted using the given image. Otherwise, "update-super" will
preserve the existing partition layout, and only ensure that logical
partition entries exist for all the new partitions in the given image.
All new partitions added this way will have a zero size, and it is the
host's responsibility to size them as needed afterwards with the
"resize-logical-partition" command.
In addition, the "update-super" command supports a "wipe" argument,
which will force the super partition to be reformatted with the given
image, overwriting any existing partition tables.
