cmd: part: Add partition-related type command
This implements the following command:
part type mmc 0:1
-> print partition type UUID
part type mmc 0:1 uuid
-> set environment variable to partition type UUID
"part type" can be useful when writing a bootcmd which searches for a
specific partition type to enable automatic discovery of partitions and
their intended usage or mount point.
