The commit (7db2fc522e) with changing behavior of builtin symbol provider
is in a conflict with a commit (72de86a8ba) where new tests were added.
The difference should be fixed as a part of KT-62651
- The semantics of a non-static declared member scope should be as
follows: For a variable `c: C` of class type `C`, the declared member
scope should contain all members `x` accessible as `c.x` (visibility
notwithstanding) which are *also* explicitly declared in `C`.
- Classifiers are not accessible as properties of a variable `c`, only
as static members of the class `C` itself, so non-static declared
member scopes should not contain any classifiers.
