Camera2: Fix broken onCaptureBufferLost callback
Turns out this never worked. 😱
- Add missing oncaptureBufferLost proxy method
- To avoid this issue in the future, change CameraDeviceImpl.CaptureCallback to be
an interface instead of an abstract class; now all implementers _must_ implement
all the methods
- For the short-circuit local callback when no callback is provided by the user,
implement all no-ops explicitly.
Test: Camera CTS continues to pass; manual testing with injected buffer drops

Camera2: Add onCaptureQueueEmpty callback
onCaptureQueueEmpty indicates that the non-repeating
capture request queue of camera device is empty, and
is ready to process a new request.
Test: testMultipleCapture in PerformanceTest.java

Camera2: Add prepare method for output buffer pre-allocation
Normally, buffers for camera output Surfaces are allocated as
needed. This minimizes memory overhead and time to first frame.
However, if allocation takes a long time, as it can do for full-resolution
output buffers, full frame rate may not be maintainable with the added
allocation overhead.
The prepare() method allows an application to indicate that buffers for
a given output Surface should be preallocated by the camera device.
Once the allocation is complete, the onSurfacePrepared callback is invoked.
The application may then use the prepared Surface without concerns about
allocation-caused delays.

Camera2: Add frameNumber to CaptureCallback#onCaptureStarted
Otherwise, cannot reliably match up capture progressed and failure callbacks
with the start callback.

Camera2: Final API revisions
- Rename listeners to callbacks. Listeners are single-method and are interfaces,
while callbacks are abstract may get more methods in the future.
- Use register/unregister for registering callbacks, not add/remove.
