feat(spmc): add FFA_PARTITION_INFO_GET handler

Enable the SPMC to handle calls to FFA_PARTITION_INFO_GET.
This allows the normal world to discover which partitions
are running in the secure world including logical partitions
in EL3.

This implementation supports both the v1.0 and v1.1
implementations of the Partition Info Get Descriptor.
The SPMC populates the appropriate descriptor in the
partitions RX buffer, if requested, according to the
version of FF-A that the caller is using.

Additionally rename the common/uuid UUID_H include guard
due to a conflict with another header file.
