Note: This is a cherry-pick of #13564 and #13259. I inadvertently broke the ghstack when attempting to re-order the stack, leading to the old PR being merged by ghstack into the ghstack-created branch (not main).

Add mman_windows.cpp to the CMake sources. Fix a few build-blocking issues with XNNPACK on Windows. Enable XNNPACK on the Windows preset. This also gives CI coverage.

I've disabled 4 microkernel families that don't build currently. These likely need to be gated or fixed upstream, but I'm disabling them locally for now to unblock usage. They are relatively niche and should have little to no perf impact on the average user.

With this change, the pybind preset works and we can re-enable it in CI.
