stm32mp: stm32prog: add support of UUID for metadata partition

Add support of UUID for metadata partition, required by Firmware update
support in TF-A:
- UUID TYPE for metadata partition: 8a7a84a0-8387-40f6-ab41-a8b9a5a60d23
- "metadata1" partition UUID: 5f91c128-e120-48d7-bb64-9fa9aed4c7e3
- "metadata2" partition UUID: f469f981-5985-4206-8fb3-839956035a65

The partition UUID is detected by the partition name:
"metadata1", "metadata2".
