Add the 4 ChromeOS GPT partition types to gpart

[allanjude]

Summary

While here, also add OpenBSD, and 2 new Microsoft partition types

[marcel]

IIRC, aliases must be sorted so that the binary search works. ms-recovery before ms-reserved, please.
I see we disordered ntfs before netbsd-* as well, so we have a pre-existing bug if the binary search still holds.

Is it a problem to re-order the enum?

Ordered the partition types alphabetically

[marcel]

I double-checked the code and there's actually no binary search logic. It's all linear. Technically speaking, the reordering was not necessary, but I really appreciate the effort. It's a lot easier now to implement a binary search for cases where the linear search gets too time consuming.

Thanks!
