Michael Kubacki 6f9838f32f MdeModulePkg/Variable: Add RT GetNextVariableName() cache support 
https://bugzilla.tianocore.org/show_bug.cgi?id=2220

This change implements the Runtime Service GetNextVariableName()
using the runtime cache in VariableSmmRuntimeDxe. Runtime Service
calls to GetNextVariableName() will no longer trigger a SW SMI
when gEfiMdeModulePkgTokenSpaceGuid.PcdEnableVariableRuntimeCache
is set to TRUE (default value).

Overall system performance and stability will be improved by
eliminating an SMI for these calls as they typically result in a
relatively large number of invocations to retrieve all variable
names in all variable stores present.
