Generate a PartitionTableModel, a PartitionTable without a disk association
Note: if label is not specified, the Press object will determine label based

1. Device booted in UEFI mode
2. A disk is larger then 2.2TiB
Most people don't care if their partitions are primary/logical
or what their gpt names are, so we'll care for them.
