VIDEO-7526: Android 12 bluetooth permissions support

[afalls-twilio]

Description

Added support for Android 12. This means the new functionality is as follows... 1) If AudioSwitch is used on an Android 12 device and the BLUETOOTH_CONNECT permission has not been granted, it will no longer crash and instead just fail to use bluetooth 2) If AudioSwitch is used on an Android 12 device and BLUETOOTH_CONNECT permission has been granted, it will work appropriately 3) If AudioSwitch is used on an Android 11 or earlier device, it will behave as it did before.

Also got test cases to run again on Android 12.

Breakdown

• BluetoothHeadsetManager has been split into an interface with two implementations, one for Android 12 and greater and the legacy version.
• Factory method for Instantiate a BluetoothHeadsetManager has been updated to construct the correct implementation of BluetoothHeadsetManager depending on the Android version
• upgraded the AndroidX.test.{orchestrator|runner|rules} to version 1.4.1-alpha03
• upgraded androidx.annotation.annotation
• upgraded junit
• upgraded the grade version

Validation

• ran enabled test cases on both an Android 12 and pre-android 12 devices.
• Modified "Ahoy" application to use AudioSwitch locally and tested on both an Android 12 and pre-Android 12 device the following cases a) When bluetooth permission is denied b) When bluetooth permissions is granted c) When bluetooth is not connected d) When bluetooth is connected

Additional Notes

Changes to Ahoy application are in a different PR.
