CameraStream has been using FrameBufferAllocator to create
FrameBuffer. FrameBufferAllocator allocats buffers using V4L2 API.
It is not allowed to allocate a new buffer while Camera runs. This
replaces the allocator in CameraStream with
PlatformFrameBufferAllocator. It allocates a buffer in a platform
dependent graphic buffer allocation API.

I confirm no regression in CtsCameraTestCases is caused with this
patch series.

  android: camera_capabilities: Add function to convert PixelFormat to
    android format
  android: camera_stream: Use PlatformFrameBufferAllocator
