feat(ops): Fast zero copy string arguments (#16777)
Uses SeqOneByteString optimization to do zero-copy `&str` arguments in fast calls. - [x] Depends on https://github.com/denoland/rusty_v8/pull/1129 - [x] Depends on https://chromium-review.googlesource.com/c/v8/v8/+/4036884 - [x] Disable in async ops - [x] Make it work with owned `String` with an extra alloc in fast path. - [x] Support `Cow<'_, str>`. Owned for slow case, Borrowed for fast case ```rust #[op] fn op_string_len(s: &str) -> u32 { str.len() as u32 } ```
