android: Introduce PlatformFrameBufferAllocator

The existing FrameBufferAllocator is not allowed to allocate a new buffer while Camera is running. This introduces PlatformFrameBufferAllocator. It allocates FrameBuffer using cros::CameraBufferManager on ChromeOS and gralloc on non ChromeOS platform. The allocated FrameBuffer owns the underlying buffer but must be destroyed before PlatformFrameBufferAllocator is destroyed.
