feat(ops): support raw pointer arguments (#16826)

See https://github.com/denoland/deno/pull/16814#discussion_r1032744083.
Allows nullable buffers in low-level ops like FFI:

```rust
fn op_ffi_ptr_of<FP>(
  state: &mut OpState,
  buf: *const u8,
  out: &mut [u32],
) 
where
  FP: FfiPermissions + 'static {
  // ..
}
```
