Trap handling for Windows ARM64

After #4990 merged, we can build wasmtime for Windows ARM64, and it should work without trap handling.

We now need to add trap handling to make it totally work.

Is this something that's being looked at actively at the moment, and would a community contribution be welcome?

No one has indicated they're working on it, so if you or anyone who is familiar with Windows on Arm is willing to build it, we'd very much welcome it!
