Subject: fix(ops): disallow auto-borrowing OpState across potential await
 point (#16952)

Fixes https://github.com/denoland/deno/issues/16934

Example compiler error:
```
error: mutable opstate is not supported in async ops
   --> core/ops_builtin.rs:122:1
    |
122 | #[op]
    | ^^^^^
    |
    = note: this error originates in the attribute macro `op` (in Nightly builds, run with -Z macro-backtrace for more info)
```
