MdeModulePkg/SetupBrowser: Load storage via GetVariable for EfiVarStore

Browse Source 
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.
