Adjusts the amount of registered external memory for the object. Used to
give V8 an indication of the amount of externally allocated memory that is
kept alive by JavaScript objects. V8 uses this information to decide when
to perform global garbage collection. Each cef_v8value_t tracks the amount
of external memory associated with it and automatically decreases the
global total by the appropriate amount on its destruction.
|change_in_bytes| specifies the number of bytes to adjust by. This
function returns the number of bytes associated with the object after the
adjustment. This function can only be called on user created objects.
