Configures Camera2 options on a `https://developer.android.com/reference/androidx/camera/core/CameraControl`.

Provides setters for dynamic capture request key-value pairs, clearing request keys, template types, and repeating capture callbacks on active camera sessions.

**Warning:** Callbacks configured on this target (such as `https://developer.android.com/reference/android/hardware/camera2/CameraCaptureSession.CaptureCallback.html`) receive raw `https://developer.android.com/reference/android/hardware/camera2/CameraCaptureSession.html` instances. Directly invoking state-altering, lifecycle, or request-submitting methods on these raw objects bypasses CameraX pipeline management and causes state desynchronization, stream freezing, or crashes. Do not invoke:

- Session lifecycle methods: `https://developer.android.com/reference/android/hardware/camera2/CameraCaptureSession.html#close()`, `https://developer.android.com/reference/android/hardware/camera2/CameraCaptureSession.html#abortCaptures()`, or `https://developer.android.com/reference/android/hardware/camera2/CameraCaptureSession.html#stopRepeating()`

- Request submission methods: `https://developer.android.com/reference/android/hardware/camera2/CameraCaptureSession.html#setRepeatingRequest(android.hardware.camera2.CaptureRequest, android.hardware.camera2.CameraCaptureSession.CaptureCallback, android.os.Handler)`, `https://developer.android.com/reference/android/hardware/camera2/CameraCaptureSession.html#setRepeatingBurst(java.util.List&lt;android.hardware.camera2.CaptureRequest&gt;, android.hardware.camera2.CameraCaptureSession.CaptureCallback, android.os.Handler)`, `https://developer.android.com/reference/android/hardware/camera2/CameraCaptureSession.html#capture(android.hardware.camera2.CaptureRequest, android.hardware.camera2.CameraCaptureSession.CaptureCallback, android.os.Handler)`, or `https://developer.android.com/reference/android/hardware/camera2/CameraCaptureSession.html#captureBurst(java.util.List&lt;android.hardware.camera2.CaptureRequest&gt;, android.hardware.camera2.CameraCaptureSession.CaptureCallback, android.os.Handler)`

- Surface / output configuration methods: `https://developer.android.com/reference/android/hardware/camera2/CameraCaptureSession.html#updateOutputConfiguration(android.hardware.camera2.params.OutputConfiguration)`, `https://developer.android.com/reference/android/hardware/camera2/CameraCaptureSession.html#finalizeOutputConfigurations(java.util.List&lt;android.hardware.camera2.params.OutputConfiguration&gt;)`, `https://developer.android.com/reference/android/hardware/camera2/CameraCaptureSession.html#prepare(android.view.Surface)`, or `https://developer.android.com/reference/android/hardware/camera2/CameraCaptureSession.html#switchToOffline(java.util.Collection&lt;android.view.Surface&gt;, java.util.concurrent.Executor, android.hardware.camera2.CameraOfflineSession.CameraOfflineSessionCallback)`
