When a module attribute was a lazy import placeholder, module attribute lookup called the module's __getattr__ before resolving it. This was needed while lazy from-imports published placeholders on the source module. That no longer happens, so the check only affected the module's own lazy imports: a catch-all __getattr__ hid them, unlike eager imports. Resolve the placeholder directly.

Module attribute lookup called the module's getattr before resolving a lazy import placeholder.
That was the fix for gh-144957, needed while lazy from imports put placeholders into the source module. gh-150052 removed that, so the check now only shadows a module's own lazy imports.
This fixes that issue and adds a new load bearing test.
