Routine Description:
This function allows a caller to extract the current configuration for one

Arguments:
This - Points to the EFI_HII_CONFIG_ACCESS_PROTOCOL.
Request - A null-terminated Unicode string in <ConfigRequest> format.
Progress - On return, points to a character in the Request string.
Points to the string's null terminator if request was successful.
Points to the most recent '&' before the first failing name/value
pair (or the beginning of the string if the failure is in the
first name/value pair) if the request was not successful.
Results - A null-terminated Unicode string in <ConfigAltResp> format which
has all values filled in for the names in the Request string.
String to be allocated by the called function.
Returns:
EFI_SUCCESS - The Results is filled with the requested values.
EFI_OUT_OF_RESOURCES - Not enough memory to store the results.
EFI_INVALID_PARAMETER - Request is NULL, illegal syntax, or unknown name.
EFI_NOT_FOUND - Routing data doesn't match any storage in this driver.
