[Cin] add Vulkan hwaccel

[Andrew Randrianasulu]

After further testing it seems that it only works reliable with HEVC
video, on my machine :(

But for hevc it really speeds things up :)

second patch adds tooltip for Vulkan decoding, and changes
pixel_format for more common for those hwaccels, hopefully.
