App, lib: Add type annotations to untyped functions

Add missing type annotations to functions that are called from typed
contexts, satisfying the new disallow_untyped_calls mypy rule.

Fixes:
- Local.py: __log() with typed parameters
- lib/App.py: _add_arguments(), add_cmd_to_parser(), add_cmds_to_parser()
- pm/rpm.py, dpkg.py: meta_map() return type
- Exec.py: __init_askpass() return type
- App.py: strip_module_from_spec(), __get_project_refs_cached(),
  ResultCache.__init__ and run(), _add_arguments()
- Added Collection type for truthy-iterable compliance
