This PR compiles an x86_64 Windows version of the runtime bitcode on an x86_64 Linux host, using Windows SDKs obtained via [xwin](https://github.com/Jake-Shadle/xwin). The resulting runtime has not yet been tested/confirmed to work on a real Windows machine, but that testing will happen later after we have updated the Savi compiler to support the Windows target (and to support cross-compilation more generally, since it's expected that for now the compiler will not be able to run on Windows directly, and will have to run within WSL and "cross-compile" to Windows). This change includes removing the old debuginfo patch and replacing it with a more general patch that allows us to inject arbitrary CFLAGS, which are needed for Windows cross-compilation beyond just the debuginfo. This patch is expected to be merged into mainline Pony (see ponylang/ponyc#4108), at which point our patch here will fail to apply and we'll need to remove it from our repo.
