BaseTools: align ERROR/WARNING/RETURN macros with MdePkg versions

BaseTools' BaseTypes.h defined the ENCODE_ERROR macro as
 #define ENCODE_ERROR(a)              ((RETURN_STATUS)(MAX_BIT | (a)))
whereas MdePkg defines it as
 #define ENCODE_ERROR(StatusCode)     ((RETURN_STATUS)(MAX_BIT | (StatusCode)))

When building with GCC 6.3 (at least) the former triggers
"error: overflow in implicit constant conversion [-Werror=overflow]"
Resolve this by aligning it with the latter one.

This also requires aligning the BaseTools typedef of RETURN_STATUS with
the MdePkg one: INTN -> UINTN.

While at it, update adjacent ENCODE_WARNING and RETURN_ERROR as well.

Add an explicit initialization of *Alignment to 0 in GenFfs.c
GetAlignmentFromFile to get rid of a warning occuring with GCC after
this change (-Werror=maybe-uninitialized).
