api!(location): avoid repeating module name in function names

E.g. rename location::is_sending_locations_to_chat to location::is_sending_to_chat.
Then import only the location module and use it with location:: prefix,
similarly to how e.g. std::fs or std::tokio::fs avoids using "fs" or "file"
in function names.
