[edk2] [patch] MdeModulePkg:Fix the issue FindQuestionFromProgress in SetupBrowserDxe is broken

[Dandan Bi]

If the storage of the question is 
EFI_HII_VARSTORE_BUFFER/EFI_HII_VARSTORE_EFI_VARIABLE_BUFFER,
in SetupBrowserDxe the configuration stings contain uppercase,but 
HiiDataBaseDxe generates the
ConfigResp string in lowercase,they mismatch,so FindQuestionFromProgress 
function is broken.
Now convert the configuration string in SetupBrowserDxe to lowercase to fix 
this issue.
