Remove BandwidthMeter from SimpleExoPlayer

The BandwidthMeter should only be used by MediaSource
instances and the objects they reference, so there's
really no reason for the player to need to know about it.

This change sacrifices DebugTextViewHelper showing the
estimated bandwidth, but I think that's a price worth
paying.
