petr-tik 2d879e0431 Stop offering private functions in completions
Before
Private functions have RawVisibility module, but were
missed because take_types returned None early. After resolve_visibility
returned None, Visibility::Public was set instead and private functions
ended up being offered in autocompletion.

Choosing such a function results in an immediate error diagnostic
about using a private function.

After
Pattern match of take_types that returns None and
query for Module-level visibility from the original_module

Fix #15134 - tested with a unit test and a manual end-to-end
test of building rust-analyzer from my branch and opening
the reproduction repository

REVIEW
Refactor to move scope_def_applicable and check function visibility
from a module

Please let me know what's the best way to add a unit tests to
nameres, which is where the root cause was
