Subject: [PATCH v2] MdeModulePkg/SetupBrowser: Load storage via GetVariable for
EfiVarStore
For EfiVarStore (EFI_HII_VARSTORE_EFI_VARIABLE_BUFFER), it will call
ExtractConfig-GetVariable-HiiBlockToConfig-ConfigToBlock when load storage
value in LoadStorage function. It's not necessary and costs lots of time to do
the conversion between config and block.
So now enhance it to call GetVariable directly.
