Add support for Windows

[garrison]

The current Yggdrasil distribution of Python does not list Windows among the supported platforms, so we are unable to support Windows until either that changes or the Python requirement is removed - see Qiskit/qiskit#14240.

To clarify, there are three potential paths forward here:

• Fix Remove libpython dependency on standalone libqiskit build qiskit#14240 upstream in Qiskit. Once this is fixed, a C API build of Qiskit will no longer depend on Python. Then, we can update the Yggdrasil build script for Qiskit_jll and build it on Windows as well.
• Make the Python package in Yggdrasil compatible with Windows. I don't know of an issue tracking this, but there is a note here about what would be involved.
• Make it configurable which Python shared library + libqiskit.so combination is used by Qiskit.jl on the user's machine. There would be some complexity about matching to a compatible Python version, and it may require compiling Qiskit, so it would not be as simple for the user. But it is probably necessary to implement this functionality at some point in order to wrap the qk_circuit_to_python function, which may be of interest to users interested to build a circuit in Julia and then transfer it to Python-land for further manipulation.
