ozone: Remove the "drm" software composited platform

ozone: Remove the "drm" software composited platform

This is a software-only platform that was used early in the process
of bringing up the Chrome OS ozone/freon (no X11) build. It's time to
remove it because it now requires not only scary flags to get it going,
but also a patch (https://codereview.chromium.org/1216303004/).

If we need a build with software rasterization let's use vgem+swrast like
our VMtests do.

BUG=531814
TEST=link still works fine with platform=gbm

What's the plan for some of the other DRM/software only files (DrmSurface,
etc...)? Are you thinking of a separate change to remove them?

They should be removed in this CL.

Updated to remove drm_surface, drm_surface_factory.cc. LMK if there are others.
