Current behavior
Currently when you have a boolean property and bind it to true|false you have to use property binding, i.e

<my-button [rounded]="true"></my-button>

Expected behavior

The following code snippet should set the rounded property to true:

<my-button rounded></my-button>

while the snippet bellow should bind it to false:

<my-button ></my-button>

What is the motivation / use case for changing the behavior?
This mimics the behavior of HTML binary attributes as well as how React threads such properties.

Of course property binding to should still works.
