Add support for serializing UUID instances to Binary subtype 4 BSON bytes directly. Users should not need to call UUID.toBinary() before using any of our APIs. This does not need to be controlled with a new option and will be added as a new feature improvement to the existing behavior. 

Acceptance Criteria

Implementation Requirements

• When calling BSON.serialize with uuid as input, it is not a requirement to convert new BSON.UUID() to binary 

Testing Requirements

• Add a test that asserts UUID.toBinary() and UUID direct serialization are always equivalent

Documentation Requirements

• Follow up with team how we want to advertise this feature
