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
