[debug] Internal dump method infrastucture

[nan-li]

Description

One Line Summary

Add OneSignal.Debug._dump method to help log different services for debugging and testing.

Details

OSDebug namespace will have _dump added, but it will be implemented in the OneSignal module instead of the OneSignalCore module where the primary implementation of OneSignalLog lives. This is so OneSignal can call sub modules to log themselves such as services in the User module.

A new protocol called OSLoggable is added with a single method to logSelf().

Motivation

• Help debug and test.
• Can be expanded in the future for SDK clients to get easily shareable information in issues reports.

Scope

Just skeleton for dumping information.

Testing

Unit testing

None

Manual testing

• Added this method to the Dev App "get tags" button and see it is triggered.

Hmm the test OneSignalNotificationsTests.testClearBadgesWhenAppEntersForeground() keeps failing in the CI but succeeds locally..

Running the CI in [Fix] Handle incorrect 404, delay making requests to new IDs which passed last week to see if something changed unrelated to this PR, and that PR fails for this now too.

Nevermind, I can revisit that test later down the line.
