    mips: Fix N32 ABI return value handling (#813)

In N32 ABI, 8-bit or 16-bit integers should be extended following the
signedness of the integer, but 32-bit integers should always be
sign-extended to 64-bit (note that N32 ABI only works on 64-bit CPUs).

So handling this in everything using libffi would be nasty.  And the
libffi code for architectures with a similar rule (LoongArch & RISC-V)
also properly handle this.  Let's do this work in libffi for MIPS N32
too.

This fixes two failures in Python 3.12.1 ctypes test.
