MdeModulePkg/Library: fix memory leak Rx/Tx Buffer in ArmFfaPeiLib
The commit e15fe066036da
("MdeModulePkg/Library: make ArmFfaPeiLib available early PEIM stage")
uses ArmFfaPeiLib in the early PEIM stage.
However, the Rx/Tx buffer allocated in the early PEIM stage uses
temporary memory. This results in a memory leak when the temporary
memory's heap is relocated to permanent memory.
For example, if the Rx/Tx buffer memory is allocated at 0x20006000
in temporary memory, and if offset between temporary memory and
permanent is 0x40000000, then:
- Once permanent memory installed the temporary memory at 0x20006000
is migrated to 0x60006000.
- However, ArmFfaPeiLib allocates new Rx/Tx buffer without freeing
the migrated Rx/Tx buffers, i.e. the buffers at 0x60006000.
This results in a memory leak as the migrated Rx/Tx buffer area is
lost.
To address this memory leak, use the MemoryAllocationHob's name, so
that the migrated memory area will be reused as Rx/Tx buffer.
This patch also includes rename ArmFfaRxTxStmm.c to
ArmFfaStandaloneMmRxTxMap.c to keep the file name convention in
ArmFfaLib with ArmFfa{Phase}{...}.c

MdeModulePkg: Make PcdFfaTxRxPageCount a PcdsFixedAtBuild PCD
The PcdFfaTxRxPageCount can never be changed dynamically
and is configured at build time to specify the size of
the Rx/Tx buffers.
Therefore, make PcdFfaTxRxPageCount a PcdsFixedAtBuild PCD.

MdeModulePkg/Library: add ArmFfaSecLib
To use Arm-FFA intereface in PeilessSec, implments
ArmFfaSecLib used by PeilessSec.
For example, communicate with TPM service using CRB over ARM-FFA
(via Tpm2DeviceLibFfa), PeilessSec need to use Arm-FFA interface.
