rCOMMd2aa8f6807a0: [services] Tunnelbroker - Add `topic` to APNs

Summary

This diff introduces changes to the A2 library wrapper to use topic for the APNs message (adding of topic argument to the wrapper function.).

When testing push notifications with the production certificate the topic for the message is mandatory. The topic is an iOS app bundle name. The topic is mandatory because some P12 certificates can have multiple app bundle names (one certificate for a few apps).

Related Linear task: ENG-1743

Test Plan

Successfully built app without errors.
Device testing:

To test the APNs notification physical iOS device is required.

Isolated testing can be done using the apns-ios-push-tester XCode project. To test it clone the apns-ios-push-tester and follow the instruction to set the certificate, run the app on the physical iOS device and get the device token.
Comm app testing can be done using the apns certificate provided in 1Password.

Send the apns message using the following library call from C++:

#include "cxxbridge_code/src/lib.rs.h"
#include "rust/cxx.h
...
const std::string cert_path = argv[1];
const std::string cert_pass = argv[2];
const std::string topic = argv[3];
const std::string device_token = argv[4];
const std::string message_body = argv[5];
const bool sandbox = true; // True if your certificate is for development.
sendNotifToAPNS(cert_path, cert_pass, topic, device_token, message_body, sandbox);

The expected result is push message delivery to the device if the credentials are correct. Errors if some of the credentials are wrong.

47 ↗	(On Diff #16432)	CXX doesn't support Option<>, that's why we are checking for whether the topic is empty or not and returning the Option here.

services/tunnelbroker/rust-notifications/src/apns.rs
12 ↗	(On Diff #16432)	the topic for the message is mandatory It seems like there's no point in calling `send_by_a2_client` when topic is None. It should be a `&str` then
services/tunnelbroker/rust-notifications/src/lib.rs
15 ↗	(On Diff #16432)	Additional context: we have `getAPNsNotificationTopic` function that determines the topic. We should probably use the value from there, probably including older clients handling.

12 ↗	(On Diff #16432)	the topic for the message is mandatory It seems like there's no point in calling `send_by_a2_client` when topic is None. It should be a `&str` then Makes sense. I've removed optional from `topic`.
services/tunnelbroker/rust-notifications/src/lib.rs
15 ↗	(On Diff #16432)	Additional context: we have `getAPNsNotificationTopic` function that determines the topic. We should probably use the value from there, probably including older clients handling. In a `getAPNsNotificationTopic` we are just hardcoded the topics: function getAPNsNotificationTopic(codeVersion: ?number): string { return codeVersion && codeVersion >= 87 ? 'app.comm' : 'org.squadcal.app'; } In the Tunnelbroker we are using the config file to provide a topic. Seems that this function is to support an old version of the app. Do we need to support the `org.squadcal.app` in the codebase of the services and hardcode it?
47 ↗	(On Diff #16432)	I would prefer a comment, so that when others stumble upon the code later, are able to find this relevant information easily. As the `topic` is no longer `Optional` we don't need to add a comment here. But it makes sense if it is. Thanks, @jon !
