StdLib: Correct two instances of mismatch between function declaration and definition causing GCC compile errors.
StdLib\Include\Containers\Fifo.h Change return type of cFIFO_Truncate to size_t. Makes declaration match definition. Update comment to describe what is returned. StdLib\LibC\Uefi\InteractiveIO\IIOutilities.c Change return type of IIO_CursorDelta to int. Makes declaration match definition. Change other types from INT32 to int, for consistency. Update comment for returned values.
