vc_image: Default YUVUV to non-tall mode, with flag if required.

Browse Source 
The HEVC block and various others don't require tall mode, it's only
the H264 codec block that has to keep the column stride below
64kB.

Switch the default configuration to NOT require tall mode.
All the users of SAND with the H264 block are currently internal
to the VPU (video decode will vc_image_convert, or pass an opaque
VC_IMAGE_T. Camera to video_encode either goes via planar, or is
passing a VC_IMAGE_T).
Add a flag to these when creating the images to request tall mode.
