Trigger reconfiguration on newly obtained MediaCodecAdapters

Add the `needsReconfiguration` API on the `MediaCodecAdapter` interface so that `MediaCodecRenderer` can reconfigure the `MediaCodec` in case a `MediaCodecAdapter` needs to be reconfigured immediately after being obtained from the `MediaCodecAdapter.Factory`.
