    This patch implements inspector support for private instance methods:
    
    - Previously to implement brand checking for instances with private
      instance methods we store the brand both as the value with the brand
      itself as the key in the stances. Now we make the value the context
      associated with the class instead.
    - To retrieve the private instance methods and accessors from the
      instances at runtime, we look into the contexts stored with the
      brands, and analyze the scope info to get the names as well as
      context slot indices of them.
    - This patch extends the `PrivatePropertyDescriptor` in the inspector
      protocol to include optional `get` and `set` fields, and make the
      `value` field optional (similar to `PropertyDescriptor`s).
      Private fields or private instance methods are returned in the
      `value` field while private accessors are returned in the `get`
      and/or `set` field. Property previews for the instaces containing
      private instance methods and accessors are also updated similarly,
      although no additional protocol change is necessary since the
      `PropertyPreview` type can already be used to display accessors.
