Component: Dropdown does not render the options that have a group property

Describe the bug

Similar to this issue #14061 Dropdown component won't render an option when it has group property. I believe the same solution to mentioned issue should be applied to Dropdown component when it's deciding which template to use.

Expected behavior

The items should be rendered OR the docs should warn that group cannot be used as a property.

Hi,

It's not a bug, you're using the component wrong and sending not supported options format for grouping. Please see the example: https://stackblitz.com/edit/ph9ucn?file=src%2Fapp%2Fdemo%2Fdropdown-group-demo.ts,src%2Fapp%2Fdemo%2Fdropdown-group-demo.html

I guess I wasn't clear. We have a lot of models in the app that have group property. For some dropdowns we use group property as label and as value, not for grouping options. Now with this update it seems like we have to rename all of the properties in our models to something else in order for them to work again?
