Create Windows CMake preset (#13257)

Create a CMake preset for Windows, based on what is currently buildable.
Add to CI. A lot of things are currently broken, including portable
kernels and XNNPACK. I've disabled these (and more) to allow setting up
the initial preset and CI. These build issues will be resolved further
in this stack.

I've also disabled the pybind preset on Windows for now, as it does not
build yet.
