ignore static and declared member if checking override

Fixes #43563
Fixes #43566

Declared property does not really override. So just ignore that.

I think I would expect that under --noImplicitOverride, overriding a static property with another static property would require the override keyword. The issue with #43563 is that it didn’t seem to recognize that static and instance properties are distinct at all. But maybe I’m missing something?

Discussed in the design meeting and decided that yes, static overrides need the override keyword in --noImplicitOverride.

Thanks @Kingwl!
