ArmPkg: MmCommunicationPei: Introduce MM communicate in PEI
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4464
This change introduced the MM communicate support in PEI phase for ARM
based platforms. Similar to the DXE counterpart, `PcdMmBufferBase` is
used as communicate buffer and SMC will be invoked to communicate to
TrustZone when MMI is requested.
