libcamera: pipeline: vimc: Switch to using the RGB/YUV Capture video node

Linux commit 85ab1aa1fac17bcd ("media: vimc: deb: fix default sink bayer
format") which is part of v5.2 changes the default media bus format for
the debayer subdevices. This leads to a -EPIPE error when trying to use
the raw capture video device nodes.

Fix this by moving the vimc pipeline to use the RGB/YUV Capture capture
video node. As a consequence of this change the scaler in the vimc
pipeline is used and a hard coded upscale of 3 is present in the video
pipeline. This limits the sizes exposed and accepted by libcamera to
multiples of 3.

Update the buffer import test case to match this  new format constraint
by setting the resolution to 1920x1080, a resolution which works with
both vimc and vivid. With this new resolution the buffer import test
takes a bit more time to complete 60 buffers and it's runtime also needs
to be increased.

The raw capture video node still needs to be handled by the pipeline as
its format needs to be updated to allow the pipeline format validation
to pass.
