liblp: Add support for updateable partition groups.
This patch introduces a new "groups" table in the super partition
metadata. Each entry denotes a named partition group with a maximum
size. All partitions now belong to a group, and the total size of
partitions in a group must not exceed its maximum size. This is enforced
by MetadataBuilder.
There is also a "default" group with no size restriction. This is used
for one-off partitions that aren't restricted by updates, for example,
the scratch partition for overlayfs, or partitions created through
fastbootd.
