Fix the SMRAM caching range base and size. The original code uses the biggest SMRAM range base and size to set the cache attribute by gDS->SetMemorySpaceAttributes(). This is not correct because the platform code might split the TSEG into several ranges. The fix searches and joins all the adjacent ranges to the biggest SMRAM range into a cacheable range so that TSEG can be cached as a whole.

Remove Size==0 branch in SmmAllocatePool()
...
The background is :
The SmmMemoryAllocationLib of one of the instance of MemoryAllocation library class. As in MdePkg comment for AllocatePool() : “If AllocationSize is 0, then a valid buffer of 0 size is returned.”,the SMM library implements AllocatePool by SMST service SmmAllocatePool which does NOT support the zero size.

Change the minimal SMM core size from 1MB to 256KB-4K.
...
Some platforms only enable 1MB, after reserve 1 page for SMM S3. There is at most 1MB-4KB for SMM core.

Update PiSmmCore:
...
1. Update PiSmmIpl.c DoCommunicate() to prevent exception in case call SmiManage directly if SMRAM is closed or locked. That case causes exception.
2. Update PiSmmCore.c SmmEntryPoint(). It is not required to save/restore InSmm. Because SMM is non-reentrant.

Add EfiCpuArchProtocol dependency for PiSmmIpl module. The reason to add this is PiSmmIpl will call gDS->SetMemorySpaceAttributes() which will locate CPU Arch Protocol to set MTRRs. Without this dependency, the locate might fail and MTRRs are never set in this case.
