Shanuj Shekhar aba15b6952 Add new APIs to ExoMediaDrm 
Changes
---
- Added `removeOfflineLicense(byte[])` and `getOfflineLicenseKeySetIds` and consumed them in their implementations

Background
---
- These APIs will help in addressing an increasing amount of `java.lang.IllegalArgumentException: Failed to restore keys: BAD_VALUE` which is our top playback error in our app
	- Based on our discussion with Widevine team and [this exoplayer issue](https://github.com/google/ExoPlayer/issues/11202#issuecomment-1708792594)
		- TL;DR: The failure occurs on startup if the user has 200+ offline licenses, we would like to add the functionality to remove offline licenses

**Note: Why we want these APIs in ExoMediaDrm and not in OfflineLicenseHelper**
	- As per the issue above, we would like to access these 2 public APIs in MediaDrm that don’t exist in `OfflineLicenseHelper` or `ExoMediaDrm`
		- APIs interested in:
			- [MediaDrm#removeOfflineLicense()](https://developer.android.com/reference/android/media/MediaDrm#removeOfflineLicense(byte%5B%5D)): To remove offline license
			- [MediaDrm#getOfflineLicenseKeySetIds()](https://developer.android.com/reference/android/media/MediaDrm#getOfflineLicenseKeySetIds()): To see number of offline licenses on startup

		- We use `OfflineLicenseHelper` to download license for L1 and we don't interact with `ExoMediaDrm` directly. But for the alternate Widevine integration, we directly depend on `ExoMediaDrm` APIs to override and call CDM Native APIs.
		- We would like to have the functionality of removing offline licenses for both integration which would need access to above APIs in `ExoMediaDrm`.

ExoPlayer module

This module provides ExoPlayer, the Player implementation for local media playback on Android.

Getting the module

The easiest way to get the module is to add it as a gradle dependency:

implementation 'androidx.media3:media3-exoplayer:1.X.X'

where 1.X.X is the version, which must match the version of the other media modules being used.

Alternatively, you can clone this GitHub project and depend on the module locally. Instructions for doing this can be found in the top level README.
