[PATCH edk2 v2 1/3] StandaloneMmPkg: Fix issue about SpPcpuSharedBufSize field

["Ming Huang" <huangming@linux.alibaba.com>]

TF-A: TrustedFirmware-A
SPM: Secure Partition Manager(MM)

In TF-A, the name of this field is sp_shared_buf_size. This field is
the size of range for transmit data from TF-A to standaloneMM when
SPM enable.

SpPcpuSharedBufSize is pass from TF-A while StandaloneMM initialize.
So, SpPcpuSharedBufSize should be rename to SpSharedBufSize and this field
should no multiply by PayloadBootInfo->NumCpus;
