core: FFA_SHARE: Process FFA_MEM_SHARE message

Process a FF-A FFA_MEM_SHARE message coming from a SP or being sent
from the Normal world with one or more SPs receivers.
FFA_MEM_SHARE is used to share a memory region from an endpoint (SP or
normal world) with one or more endpoints in secure world(SPs).

A simplified version of the share memory transaction descriptor looks
like the following:

|-------------------|
|ffa_mem_transaction| Contains general data for the whole share
|-------------------|
|mem_access_array[0]| Contains information specific for each receiver SP
|-------------------|
|mem_access_array[1]|
|-------------------|
|mem_access_array[n]|
|-------------------|
|ffa_mem_region | Contains the memory which is shared
|-------------------|

Add sp_mem as a new memory object. Sp_mem is used to store all
information needed for a FF-A share. For each new FF-A share a sp_mem
object is created. Each share is stored inside the mem_shares list
inside sp_mem.c

The ffa_mem_transaction data is stored inside the sp_mem object.
The receivers list inside sp_mem is used to store all the
ffa_mem_region related data.
The regions list is used to store all data related to the
mem_access_array. A mobj reference is will be used to map the region
into the SPs endpoint.

ftrace: Add support for syscall function tracer

This patch adds support for syscall tracing in TEE core. It complements
existing ftrace support for user TAs via adding trace for syscalls that
are invoked by user TAs into the TEE core.

And after this patch ftrace will cover both TA and TEE core code. So lets
rename config option from CFG_TA_FTRACE_SUPPORT to CFG_FTRACE_SUPPORT.

It is optional to enable syscall trace via CFG_SYSCALL_FTRACE=y config
option in addition to CFG_FTRACE_SUPPORT=y config option.
