Subject: [PATCH] Adapt event injection to Android 13

Using the "input" service results in a permission error in Android 13.

Use the InputManager instance (retrieved by InputManager.getInstance())
instead.

Fixes #3186 <https://github.com/Genymobile/scrcpy/issues/3186>
PR #3190 <https://github.com/Genymobile/scrcpy/pull/3190>
