Missing includes for faiss when building for Android x86-64

[DavidVentura]

Bug description

faiss does not build on x86-64

How to reproduce

Include marian-dev in a CMake project (in my case, Android) and hit build.

You will get

error: unknown type name '__m128'
  148 | static inline __m128 masked_read(int d, const float *x)
      |               ^

This patch solves the issue

diff --git a/src/3rd_party/faiss/VectorTransform.h b/src/3rd_party/faiss/VectorTransform.h

Also reported upstream

Maybe masked_read should be gated by #ifdef __AVX__ instead of #ifdef __SSE__ ?
