MediaCodecInfo.java: Added isFeatureSupported method to CodecCapabilities

Added isFeatureSupported method to CodecCapabilities, so that applications
can query whether codecs support various features.  For now
added one video-decoder feature:

FEATURE_AdaptivePlayback

Media playback applications can query it to see if the codec
supports seamless resolution changes during decoding.
