1933787 - Implement object previews/grips in C++

Status: ASSIGNED

(DevTools :: Debugger, enhancement)

Description

[Alex Thayer [:alexical] (she/her)]

Basically, creating previews for objects is rather expensive, and can be made much faster if implemented in C++. Simply migrating the existing JS logic into C++ is a significant speedup, but there's also more work we can do by serializing the preview into a binary representation which can be more efficiently passed to the parent process and included in profiles / elsewhere. This bug tracks at least the first part of this, and it may be most expedient to just do the serialization work as part of this.
