analyzer: mark fewer types in variable declarations and is-expressions as "used"

analyzer already considers `foo is _A` to _not_ be a use of class _A.
This change makes this policy more consistent by considering code like
`foo is List<_A>` to also not be a "use".

The same is true for non-field variable declarations like `_A? foo;`,
which now includes `List<_A>? foo;`.
