Change behaviour of DotVVM02 warning for overrides

[liviriniu]

Taken from the forum post DotVVM02 warning for overrides

I saw that decorating the property in the abstract base (while making the warning go away which is correct), has effect on the override property, Bind not being needed to be set also on it. So I thought of suggesting a tweak to you for the behaviour of the DotVVM02 warning - to not be signaled on overrides which inherit the Bind attribute.
