Summary: Similar to what lld already does for dllimport symbols which are prefaced with __imp_ (see lld patch r240620), strip off the __imp_ prefix in LTO. Otherwise we can get 2 separate GlobalResolution for a single symbol, the dllimport declaration, and the definition, which leads to incorrect LTO handling. Fixes PR38105.
