Stores the test/bench functions in rust op state during registration. The functions are wrapped in JS first so that they return a directly convertible `TestResult`/`BenchResult`. Test steps are still mostly handled in JS since they are pretty much invoked by the user. Allows removing a bunch of infrastructure for communicating between JS and rust. Allows using rust utilities for things like shuffling tests (`Vec::shuffle`). We can progressively move op and resource sanitization to rust as well. Fixes #17122. Fixes #17312.
