Remove single param Mid() method from string classes
This support is being removed from CFX_ByteString, CFX_ByteStringC, CFX_WideString, and CFX_WideStringC. This standardizes all of these classes to only have one Mid method that takes in 2 params, offset and count. Count now must be positive. The old behaviour of calculating the length for the user if -1 is passed in for the count has been removed. This work is in preperation for converting these classes to not accept negative lengths anywhere and thus make the underlying size type unsigned.
