feat(ops): fast calls for Wasm (#16776) This PR introduces Wasm ops. These calls are optimized for entry from Wasm land. The `#[op(wasm)]` attribute is opt-in. Last parameter `Option<&mut [u8]>` is the memory slice of the Wasm module when entered from a Fast API call. Otherwise, the user is expected to implement logic to obtain the memory if `None` ```rust #[op(wasm)] pub fn op_args_get( offset: i32, buffer_offset: i32, memory: Option<&mut [u8]>, ) { // ... } ``` 2022-11-27 08:54:28 -05:00			`// Copyright 2018-2022 the Deno authors.
