Previously `MediaPeriodQueue` would return null if an ad media URI hadn't loaded yet, but this meant that the player could be stuck in `STATE_READY` if an `AdsLoader` unexpectedly didn't provide an ad URI. Fix this behavior by masking ad media periods. `MaskingMediaPeriod` no longer requires a `MediaSource` to instantiate it. This also fixes a specific case where playback gets stuck when using the IMA extension with an empty ad where the IMA SDK unexpectedly doesn't notify the ad group fetch error.
