refactor(memory share): reclaim from other world
The memory reclaim has been refactored to better differentiate
SPMC's and Hypervisor's implementation.
The functions that operate a memory reclaim targetting the other
world, are moved to the plat/ffa module:
- The SPMC returns ffa_error(FFA_INVALID_PARAMETER), as it considers
to have received an invalid memory handle.
- The Hypervisor delegates the tracking of the memory region to
the SPMC if there is a SP involved, either as the Sender or as
a receiver. As such, all functions doing memory reclaim with
the other world (i.e. the secure world) that were defined in
`ffa_memory.c` have been moved to `plat/ffa/hypervisor.c`.
Few functions from ffa_memory.c were made public to be
invoked in 'plat/ffa/hypervisor.c'.
