bpo-35108: handle exceptions in inspect.getmembers

[TomAugspurger]

Makes inspect.getmembers robust to classes that raise exceptions
other than AttributeError in properties.

In https://bugs.python.org/issue35108, @tirkarthi suggested using getattr_static for these types of properties. It would also suggested that

there might be still cases where getattr_static triggers an exception too where we need to decide whether to skip the attribute from being listed and if so with a test for the scenario.

I wasn't able to construct a test case that raised an exception in getattr_static, so I haven't implemented the suggestion that we skip the attribute in this case. Happy to add a test case if anyone is able to provide some guidance.
