  [flang] Suppress USEs of non-USE'able names in module files (#124980)

When harvesting and formatting symbols USE'd from other modules, don't
emit USE statements to module files for names unless they come from the
topmost scope of the module. There was a check to prevent names from
derived type scopes from escaping in this way, but it must be made more
general to prevent other cases like dummy arguments in interfaces.

Fixes https://github.com/llvm/llvm-project/issues/124716.
