Creates a new value update
specifying the removal of all values in a given list from an array or weighted set. Note that this method
is just a convenience method, it simply iterates
through the list and creates value updates by calling createRemove() for each element.

@param values a List containing the values to remove
@return a List of ValueUpdates specifying the removal
@throws IllegalArgumentException      if the runtime type of values does not match the type required
@throws UnsupportedOperationException if the field type is not array or weighted set
