Opentok 47720 - Update samples for Android SKD regarding the use of Custom Audio Driver and READ_PHONE_STATE permission

[goncalocostamendes]

What is this PR doing?

READ_PHONE_STATE permission is needed, on versions built targeting API level 31 can react appropriately to incoming and outgoing calls. In case the permissions are not granted, to prevent a crash, validations of current version were added.

How should this be manually tested?

Configure following versions:

• Android API >= 31;
• OpenTok >= 2.22.0

Run samples mentioned below on Android Studio:

• Advanced Audio Driver Java;
• Advanced Audio Driver Kotlin;
• Phone Call Detection Java;
• Phone Call Detection Kotlin;

For each one, verify if when connecting and publishing using Playground, the app does not crash.
