SecurityPkg: Tcg2AcpiFfa: Correct TPM Instance Validation
The current implementation checks `PcdTpmInstanceGuid` and enforces the
use of the DTPM instance GUID. However, for FFA-specific modules, the
correct value should be `gTpm2ServiceFfaGuid`.
This update fixes the validation logic to support routing through
Tpm2DeviceLibRouter* with the appropriate instance library, which
requires the instance ID to be set to `gTpm2ServiceFfaGuid`.

SecurityPkg: Tcg2StandaloneMmArm: Enable TPM FFA Instance to Register PPI
Previously, the implementation restricted usage to TPM instances with the
DTPM ID, which worked only if the system supported TPM over FFA but still
set the instance ID to DTPM. However, Tpm2InstanceLibFfa requires the
`PcdTpmInstanceGuid` to be set to `gTpm2ServiceFfaGuid`.
This update expands support by allowing the `PcdTpmInstanceGuid` to
include the TPM-over-FFA instance GUID, enabling proper registration of
the PPI.
