Reland "Reland "gpu: Support arbitrary transforms in OverlayCandidate""

This is a reland of commit 329443961a4d934457364046d0c72e709a04eff5

The previous reland was failing in configurations without `DCHECK_ALWAYS_ON`, causing the death tests to fail. In this CL, we've wrapped the death tests with `DCHECK_IS_ON() && defined(GTEST_HAS_DEATH_TEST)` to avoid running the tests when they are not supported.

> Original change's description:
> > gpu: Support arbitrary transforms in OverlayCandidate
> >
> > Allow for an OverlayCandidate to store a gfx::Transform instead of
> > attempting to bake it into its |display_rect| and extract a
> > gfx::OverlayTransform. This allows platforms that support delegated
> > compositing for quads with arbitrary transforms such as rotation,
> > scaling, etc using OverlayCandidate.
> >
> > |display_rect| is now documented to be explicitly in content space,
> > where |transform| is the content to target space transformation.
> > |transform| can now be either a gfx::OverlayTransform or a
> > gfx::Transform. When it is a gfx::OverlayTransform, it only affects the
> > orientation of the buffer within |display_rect|'s bounds.
> >
> > Some platforms do not support clip rects, so OverlayCandidateFactory
> > bakes the clip and visible rects into the display and uv rects. This
> > would not be possible if the overlay's transform does not preserve 2d
> > axis alignment. There are no platforms expected to support arbitrary
> > transforms but not clip rects, so we've decided to simply DCHECK in
> > these cases rather than attempt to handle them.
