MdeModulePkg/FaultTolerantWriteSmm: Update buffer valid check func name
In the MdeModulePkg/FaultTolerantWriteSmm, the Primary Buffer
(CommBuffer) check function has been updated to match the buffer
validation behavior:
For SMM, the SMM Handlers is to validate the buffer outside MMRAM.
For MM, the MM Handlers do not need to validate the buffer if it is
the CommBuffer passed from MmCore through the MmiHandler() parameter.
Return TRUE directly in this case.
There is no function impact.

MdeModulePkg/VariableSmm: Fix NonPrimary Buffer check issue
VariableSmmIsBufferOutsideSmmValid function is to check the buffer

true for MM.
Meanwhile, this patch renames VariableSmmIsBufferOutsideSmmValid
to VariableSmmIsNonPrimaryBufferValid.

SecurityPkg/Tcg: Correct buffer valid check func
For SMM, the SMM Handlers is to validate the buffer outside MMRAM
including the Primary & NonPrimary buffer.
For MM, the MM Handlers do not need to validate the Primary buffer
if it is passed from MmCore through the MmiHandler() parameter.
Return TRUE directly in this case. But need to validate NonPrimary
buffer that outside MMRAM.
