Fix ExoMediaCryptoType attachment

- Attach types for placeholder sessions. If a placeholder session will be
  attached and a downstream renderer doesn't know what to do with it, then
  this attachment is necessary to correctly determine that the renderer
  does not support the track.
- Attach types to sample formats. Without this, if playback fails due to
  a CryptoException, the ExoPlaybackException that gets thrown spuriously
  indicates that the format's DRM type was not supported.
