disable jit unwind handling on aarch64 windows
As the comment for SetJitExceptionHandler makes clear, the infrastructure we have for generating unwind information on 64-bit Windows is only necessary to permit Breakpad to generate crash reports. We don't even have crash reporting for our non-existent AArch64 Windows builds, and it will likely take us some time to make the necessary changes in Breakpad and elsewhere. In addition, the unwind information format is completely different on AArch64, and there's no decent documentation on it yet. Given all of this, the easiest way forward right now is to simply disable this code to get things compiling. We can reenable it later once we understand how to add appropriate support.
I don't particularly like doing this, but I'm open to better options.

Comment on attachment 8999042 [details] [diff] [review] disable jit unwind handling on aarch64 windows Seems reasonable. Maybe file a follow-up bug blocking the relevant ship-on-windows-aarch64 bug just to make sure we double check this eventually?
