Ensure that at most one mutable Isolate reference exists at a time. `deno_execute()` and `deno_respond()` now borrow a reference to the rust-side isolate from the caller. When we need a reference to the isolate while one of these functions is on the stack, `deno_get_data()` can be used to borrow back that reference.
