Plumb a surface destruction callback for AVDAs on Android

This plumbs the SurfaceHolder.Callback#surfaceDestroyed() callback,
that comes from the Android framework when our video SurfaceView surface
is being destroyed, from the Browser UI thread to the GPU main thread.
The code to handle this callback in AVDA will be added in a future CL.

It's not ideal that we have to do this, but we don't really have a choice.
We don't control the lifetime of SurfaceView surfaces directly, so we have
to be prepared to handle their destruction.

Currently, AVDA handles the loss of surface by not immediately reporting
an error when its MediaCodec starts throwing IllegalStateException. In
some cases, the ISE is due to losing the surface, and in others it's a
real error. By deferring reporting the error to the VDA client, the client
has a window of time where it can Destroy the VDA (which it does on
fullscreen transitions) without seeing the error.

However, on JB devices it's not enough to defer errors. Letting the
surface be destroyed while the MediaCodec is still active can cause it
to hit an internal CHECK, which kills the GPU process. So this CL
introduces a path for AVDAs to get a synchronous callback in which they
can tear down their MediaCodecs before the surface is destroyed (which
is what the surfaceDestroyed() callback is for).

media: Handle output SurfaceView destruction in AVDA

Previously AVDA didn't get a callback when its output surface was being
destroyed. Now, with AVDASurfaceTracker, AVDA registers for a callback
in which it releases its MediaCodec to avoid putting MediaCodec into
an invalid state that can causes crashes in some cases.

This also disables AVDA VP8 for api levels 16 and 17, because on those
platform versions we have to fully flush the MediaCodec before
releasing it, and that's something we don't want to handle in the
surface destruction callback.
