AudioTimer to use Coroutines

[criticalAY]

Purpose / Description

I am preparing Audio timer to be used in notification i.e. allow update every 1s for notification as ms updates are too much and Android ignore them, it also removes interfaces and uses modern lambdas to observe time and update it in UI

• Moving Timer class to recorder package as I want to create a separate view and remove any coupling from other classes so recorder logic is contained in one package
• Add param for notification updates
• Removed interface
• Improved how time is updated

Fixes

NA

Approach

Replaces the legacy Handler/Runnable implementation with Kotlin Coroutines

How Has This Been Tested?

Pixel Fold API 36 and unit tests

Learning (optional, can help others)

The first commit shouldn't have a 'refactor' message IMO - it's borderline
