Apple's upcoming arm64 devices will prevent rwx access to memory, but in turn provide a new per-thread way to switch between write and execute permissions. This patch puts that system to use for the WebAssembly subsystem. The approach relies on CodeSpaceWriteScope objects for now. That isn't optimal for background threads (which could stay in "write" mode permanently instead of toggling), but its simplicity makes it a good first step.
