Add type validators to nested components

Description

There is no type validators (prop-types and typescript declarations) in nested components now. It will be nice to have it.

Current Behavior

for example:

class Editing extends NestedOption<{
  allowAdding?: any;
  allowDeleting?: any;
  allowDragging?: any;
  allowResizing?: any;
  allowUpdating?: any;
}> {
  public static OptionName = "editing";
}

Expected Behavior

class Editing extends NestedOption<{
  allowAdding?: boolean;
  allowDeleting?: boolean;
  allowDragging?: boolean;
  allowResizing?: boolean;
  allowUpdating?: boolean;
}> {
  public static OptionName = "editing";
}

We will consider this enhancement in the future, but I can't provide any timeframe.
