Original commit message: [wasm][mac] Support w^x codespaces for Apple Silicon 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.

Original commit message: [platform] Add Permission::kNoAccessWillJitLater enum value This value is unused for now. This CL is part 1 of a 3-step dance.

Original commit message: [mac] Set MAP_JIT only when necessary This is a "minimal" change to achieve the required goal: seeing that there is only one place where we need to indicate that memory should be reserved with MAP_JIT, we can add a value to the Permissions enum instead of adding a second, orthogonal parameter. That way we avoid changing public API functions, which makes this CL easier to undo once we have platform-independent w^x in Wasm.
