libparted: Add ChromeOS Kernel partition flag
This adds a GPT-only partition type flag, chromeos_kernel, for use on
Chrome OS machines, with GUID FE3A2A5D-4F32-41A7-B725-ACCC3285A309.
The firmware/bootloader in these machines relies on special images being
written to partitions of this type. Among multiple such partitions, it
decides which one it will boot from based on the GUID-specific partition
attributes. This patch is not intended to and does not manipulate these
bits.
Google refers to these partitions as "ChromeOS kernel" partitions. They
also define partitions for rootfs, firmware, and a reserved one; but
these are not necessary for the boot flow and are not included here.
