Windows Arm64 support

[Binozo]

Hey there 👋

currently I am working on a project using faiss using FaissMask (.NET Bindings).
As I am developing on a windows arm64 machine I needed a way to compile faiss for windows arm.
I ran the tests in FaissMask and my little hack seemed valid.

Here is a little script to compile it yourself:

#!/bin/bash
# Execute in git bash
# and cmake (https://cmake.org/download/)
BRANCH="feat/windows-arm64-support"
GITHUB_ACCOUNT=Binozo

git clone --depth=1 --recursive --branch $BRANCH https://github.com/$GITHUB_ACCOUNT/faiss.git
cd faiss
cmake -Wno-dev -DFAISS_ENABLE_GPU=OFF -DFAISS_ENABLE_PYTHON=OFF -DFAISS_ENABLE_C_API=ON -DBUILD_TESTING=OFF -DBUILD_SHARED_LIBS=ON -DCMAKE_WINDOWS_EXPORT_ALL_SYMBOLS=ON -DBLA_VENDOR=Intel10_64_dyn "-DMKL_LIBRARIES=C:\Users\<USER>\CLionProjects\OpenBLAS\cmake-build-release\lib\Release\openblas.lib" -B build -S .
cmake --build build --config Release --target faiss faiss_c

(Make sure you compiled OpenBLAS for windows arm64 before and adjust C:\Users\<USER>\CLionProjects\OpenBLAS\cmake-build-release\lib\Release\openblas.lib if needed)

HI @Binozo This doesn't appear to be Windows specific actually. Does it do the same thing for aarch64 as the above code for x86-64?
