V4L2DecodeComponent: Support protected playback.

In this CL, V4L2DecodeComponent supports the protected playback by
using C2VdaBqBlockPool. To use C2VdaBqBlockPool, there are 2 specific
requirements compared to a normal C2BlockPool:
1. Call C2VdaBqBlockPool::requestNewBufferSet() before fetching blocks
2. Call MarkBlockPoolDataAsShared() after creating C2ConstGraphicBlock

Test: Run ExoPlayer Demo apk: Widevine dash policy tests
