Modified SurfaceView and ViewRootImpl to provide callbacks when syncing
a transaction instead of sending transactions. This will ensure a clear
ownership of the transaction object since it will be provided in the
callback when BBQ adds a buffer into the transaction. Modified JNI to
add compatibility for native functions.
Test: Manual testing from go/wm-smoke.
Test: BLASTBufferQueueTest
