Michael Kubacki f3b2187d55 MdeModulePkg/VariablePolicy: Add more granular variable policy querying
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.
