Remove visibility.all from @component annotations. This is potentially BREAKING

change.

Please review carefully. Breakage will only be caught if the code is covered by
tests. Reject this change if you believe it breaks you.

If the component needs to be injected anywhere in the app, you can get a
runtime exception after this change. This should be caught by tests using your
components, and fixing the issue should be trivial, as the exceptions have good
error messages, such as "No provider found for FooComponent".
