update_payload: Allow specifying partition options for major version 2
This commit adds the ability to specify partition options for more than just
kernel/rootfs.
This supersedes -p/--root-part-size, -P/--kern-part-size, --dst_kern,
--dst_root, --src_kern, --src_root, --out_dst_kern, and --out_dst_root.
They are replaced by --part_names used in conjunction with --part_sizes,
--dst_part_paths, --src_part_paths, and --out_dst_part_paths.
Backwards-compatibility with the old flags is kept, so long as they are
not used alongside the new flags.
BUG=b:794404
TEST=no errors during run_unittests and test_paycheck.sh
