Improve 'super' partition description in back-up menu.

For the back-up menu, we can detail what the super partition includes by
aggregating one of BOARD_GOOGLE_DYNAMIC_PARTITIONS_PARTITION_LIST or
BOARD_QTI_DYNAMIC_PARTITIONS_PARTITION_LIST.

We comma-separate the list and capitalise the first letter of each
dynamic partition.
