SecurityPkg: Implement AuthVariableLib library instance

Browse Source 
What to do:
1. Implement AuthVariableLib library instance.
2. Temporarily add VARIABLE_ENTRY_CONSISTENCY and
variable attribute combinations definitions to
AuthenticatedVariableFormat.h for git bisect.

Why to do:
1. Share code.
Separate auth variable service from Auth Variable driver in
SecurityPkg to AuthVariableLib. Then the AuthVariableLib could benefit
and be used by different implementation of Auth Variable drivers.
