Offer a Suspending API for `EncryptedLogging.enqueueSendingEncryptedLogs(...)`

[ParaskP7]

This came as an idea after working on WCAndroid#14711, where we identified a limitation of using appCoroutineScope.launch { ... } with encryptedLogging.enqueueSendingEncryptedLogs(...) for FATAL errors.

FYI: Another idea to address this issue, from a different angle, could be:

• In case of FATAL error, store an "intent" of sending logs in the future.
• On the next app resume, check the "intent" and collect logs then (because they’re stored now on the disk).
