[CodeCompletion] Don't check 'InvalidAsyncContext' for imported globals
'InvalidAsyncContext' depends on the decl context. That may case "sticky" not-recommended If it's cached for a non-async context. To workaround this, stop checking 'InvalidAsyncContext' when collecting completion items for caching. Also consistently use the 'SourceFile' as the decl context to avoid decl context specific behavior. rdar://78315441
