In the MdeModulePkg/VarCheckPolicyLib, 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. Existing code is incorrect for
the MM check. This will be fixed in the following patch.
There is no function impact.

Introduces two new APIs to EDKII_VARIABLE_POLICY_PROTOCOL:
1. GetVariablePolicyInfo()
2. GetLockOnVariableStateVariablePolicyInfo()
These allow a caller to retrieve policy information associated with
a UEFI variable given the variable name and vendor GUID.
GetVariablePolicyInfo() - Returns the variable policy applied to the
UEFI variable. If the variable policy is applied toward an individual
UEFI variable, that name can optionally be returned.
GetLockOnVariableStateVariablePolicyInfo() - Returns the Lock on
Variable State policy applied to the UEFI variable. If the Lock on
Variable State policy is applied to a specific variable name, that
name can optionally be returned.
These functions can be useful for a variety of purposes such as
auditing, testing, and functional flows.
Also fixed some variable name typos in code touched by the changes.

__FUNCTION__ is a pre-standard extension that gcc and Visual C++ among
others support, while __func__ was standardized in C99.
Since it's more standard, replace __FUNCTION__ with __func__ throughout
MdeModulePkg.
