Port v4l2_device for decoder from Chromium
file: src/media/gpu/v4l2_device.*
generic_v4l2_device.*
1) combine v4l2_device and generic_v4l2_device
2) only decoder part is reserved to make porting simpler
3) remove EGLImage-related codes
file: src/media/base/video_codecs.*
video_types.h -> video_pixel_format.h
1) only reserve code part where we use
2) rename to video_pixel_format.h since we only need that on video_types.*
file: src/media/video/video_decode_accelerator.*
1) temporarily port SupportedProfile part only to make v4l2_device workable
file: videodev2.h
This header file is obtained from ChromeOS which is not upstreamed in Linux
mainline. This file should be removed once it is upstreamed.
Bug: 32691050
Test: 1) mmm external/v4l2_codec2
2) test some functions (e.g. Open, Ioctl, GetSupportedResolution...) by
ARC++ on nyc branch
