Add "Pause audio" action

[snowtimeglass]

Purpose / Description

I have read several requests/suggestions on GitHub/Forums/Play Store for the "Pause audio" feature, which already exists in the desktop version and AnkiMobile. For example:

• Add audio actions (Anki Forums)
• Adding "pause" audio to AnkiDroid #6774

Approach

• Add “Pause audio” feature for sound tag playback, as an intermediate goal to implementing “Pause media”, which can also pause video playback.
• Add the feature to the new study screen, without touching the legacy study screen (from the viewpoint of maintainability)
• Use the conventional ”Suspend” icon for the "Pause audio"
  • Allocate a different icon for the "Suspend" item
• Change the "Pause audio" item's icon and label when sound is being paused
  • "Pause audio" -> "Resume audio"
• Disable the "Pause audio" item when a video playback or a TTS playback starts

How Has This Been Tested?

Tested on a physical device (Android 15 / SDK 35)

The feature never got accepted and it was barely discussed. There weren't even a participation of a maintainer there. I know that it is an Anki feature, but that doesn't justify the complexity here.

And right now the new study screen is under a stabilization phase, not a phase for adding new features.

Also, being frank, the code quality here isn't great. It may sound harsh, but it is a step back in terms of code complexity and cleaness, while my current goal is to improve testing in the new study screen, so cleanups and refactors are possible without risking too much breaking things.

I'll do the hard move of drafting the PR, since I don't think this is reviewable at the moment, nor any time soon.
