[COMMITTED 097/144] gccrs: imports: Start storing Ribs in ImportKind

[arthur . cohen]

From: Arthur Cohen <arthur.co...@embecosm.com>

gcc/rust/ChangeLog:

        * resolve/rust-late-name-resolver-2.0.cc (Late::visit): Add debug call.
        * resolve/rust-toplevel-name-resolver-2.0.cc (TopLevel::visit): Store
        imports using the new classes.
        * resolve/rust-toplevel-name-resolver-2.0.h: Use new classes.
