feat(trp): test el3-rmm ide km interface

This patch introduces test functions to the Test Realm Payload (TRP)
for performing basic sanity checks on the RMM-EL3 IDE KM support added
to EL3.

The primary goal of this patch is to only to verify the basic
functionality and ensure the implemented functions return the
correct return values.

The test uses random values for the ecam address, rootport ID,
IDE stream info, keys, and IV values.

fix(trp): preserve RMI SMC X4 when not used as return

This patch adds X2-X6 and 'smc_ret' parameters to trp_rmi_handler().
The last 'smc_ret' parameter passed in X7 contains address of
'trp_smc_result' structure on stack to return result of RMI SMC call.

This allows to preserve X4 if not used as a return argument as per
SMCCCv1.2. The patch also removes use of trp_args_t in RMI handling.

feat(rmmd): add support for RMM Boot interface

This patch adds the infrastructure needed to pass boot arguments from
EL3 to RMM and allocates a shared buffer between both worlds that can
be used, among others, to pass a boot manifest to RMM. The buffer is
composed a single memory page be used by a later EL3 <-> RMM interface
by all CPUs.

The RMM boot manifest is not implemented by this patch.

In addition to that, this patch also enables support for RMM when
RESET_TO_BL31 is enabled.

refactor(rme): reorg existing RMMD EL3 service FIDs

This patch reworks the GTSI service implementation in RMMD
such that it is made internal to RMMD. This rework also
lays the ground work for additional RMMD services which
can be invoked from RMM.

The rework renames some of the FID macros to make it
more suited for adding more RMMD services. All the RMM-EL31
service SMCs are now routed via rmmd_rmm_el3_handler().

feat(rme): add Test Realm Payload (TRP)

TRP is a small test payload that implements Realm Monitor
Management (RMM) functionalities. RMM runs in the Realm world
(R-EL2) and manages the execution of Realm VMs and their
interaction with the hypervisor in Normal world.

TRP is used to test the interface between RMM and Normal world
software, known as Realm Management Interface (RMI). Current
functions includes returning RMM version and transitioning
granules from Non-secure to Realm world and vice versa.
