wic: add 'part-name' argument for naming GPT partitions

The WIC's 'part' can now give a name for GPT partition in WKS file.
It's similar to '--label', but is naming partintions instead file systems.
It's required by some bootloaders to partitions have specified names.

Backport from master, without it WIC cannot be used on Qualcomm based machines.
