`toMatchObject` and some asymmetric matchers (#3260)

* `toMatchObject` progress

* add `expect.stringContaining()`

* add `expect.stringMatching()`

* print asymmetric matchers

* cleanup

* return before printing if constructor value isn't there

* move matcher logic to cpp

* pretty format and tests

* fix formatting for snapshots

* format `stringContaining` and `stringMatching` like jest

* better test

* remove commented tests

* remove old property matcher code

* add types

* make sure all props are matched in arrays

* add `Bun.deepMatch`
