[Build] libXNNPACK.a not built when building with vcpkg and onnxruntime_BUILD_UNIT_TESTS=off

[cyanic-selkie]

Describe the issue

When building onnxruntime==v1.20.0 with the XNNPACK EP using vcpkg, the libXNNPACK.a doesn't get built. It gets built normally when not using vcpkg.

build/linux/Release/_deps/googlexnnpack-build/CMakeFiles/XNNPACK.dir exists, but the built library itself doesn't.

It turns out that the root cause for this is actually the onnxruntime_BUILD_UNIT_TESTS=off. If I leave it out, it actually tries to build XNNPACK, but fails with the logs below.
