feat(partition): add interface to init gpt
Current interface 'partition_init' accepts parameter image_id
and returns no value. But the entire partition driver is build
only to parse and handle GPT partitions, so add new interface
gpt_partition_init which would return failure to platform code
if it fails to parse the image.

feat(partition): add support to use backup GPT header
Currently we just use primary GPT header which is located in second
entry after MBR header, but if this block is corrupted or CRC
mismatch occurs we could try to use the backup GPT header located at
LBAn and GPT entries following this from LBA-33.
Add suitable warning messages before returning any errors to identify
the cause of issue.

feat(partition): add a function to identify a partition by GUID
With the GPT partition scheme, a partition can be identified using
it's UniquePartitionGUID, instead of it's name. Add a function to
identify the partition based on this GUID value. This functionality is
useful in identification of a partition whose UniquePartitionGUID
value is known.

feat(partition): make provision to store partition GUID value
The FWU multi bank feature supports multiple partitions or banks of
firmware components, where a platform can support having an active and
a backup partition(bank) of firmware images to boot from. This feature
identifies the images in a given bank using image GUID's --
this GUID value corresponds to the UniquePartitionGUID value used to
uniquely identify a GPT partition.
To support identification of images, add a member to the
partition_entry structure to store the UniquePartitionGUID value of
the GPT partition entry. This value is subsequently used to select the
firmware image to boot in a multi partition setup.
