Remove glUtil.clearOutputFrame from GLObjectsProvider.

https://github.com/google/ExoPlayer/commit/ddbad570311fec7df635b0b6da9083be82291b50 added clearing depth buffers to GLUtil, so there is no need to have allow apps to have a custom clearOutputFrame.
Also removes default implementations in GLObjectsProvider know that these methods have been implemented.
