Remove stale eagle_unit dependencies from library/ (#5477)

Remove unused eagle_unit deps from resolved_eagle_unit and
province_conquered_action. These files use ResolvedEagleUnit (which
uses Scala types), not EagleUnit (which uses proto types).

This breaks the transitive proto dependency chain, reducing library/
proto deps from 74 to 41.
