drm_hwcomposer: Support assigning planes in ValidateDisplay
In order to assign planes to layers in ValidateDisplay, testing
compositing with a DRM atomic modeset test is needed as PresentDisplay
is too late. This means most of PresentDisplay needs to be run from
ValidateDisplay, so refactor PresentDisplay to a common function adding
a test only option.
