vrana 4682e0c104 Warn against writing to undeclared properties
Summary:
I make this error quite often: I forget to declare a property I am writing to or I make a typo in it.
PHP implicitly creates a public property which I don't like.

I would much rather see a linter warning me against this than this runtime check but writing it is very difficult:

- We need to explore all parents of the class we are checking.
- It is even possible that children will declare that property but it's OK to treat this as error anyway.
- We can extend also builtin or external classes.
- It's somewhat doable for `$this` but even more complex for any `$obj` because we don't know the class of it.

This should catch significant part of these errors and I'm fine with that.

I don't plan escalating to exception because this error is not fatal and should not stop the application from working.

Test Plan: Loaded homepage, checked log.
