Add tests excercising switching between various scaled/unscaled
transitions to and from various nv12 formats, since some of the
workarounds mention this may fail.

We also add NV12 specific clipping/scaling tests, to make sure
that YUV src coordinates are always programmed as a multiple of 2
correctly, and verify scaling/clipping works with CRC tests.

crop-scale-bug shows a corruption when scaling and cropping at the
same time.

The subpixel clip test rotates and clips a rectangle on each side,
which should produce the same CRC as when that part of the rectangle
is hidden by a cursor and a whole 2x2 pixel is hidden.

Changes since v1:
- Reset plane position to 0,0 at the start of yuv_valid_width_plane().
- Handle Swati's feedback.
Changes since v2:
- Skip 90°/270° rotation in tests when formats don't support it.
- Add all new HDR formats to test.
- Use igt_plane_has_format_mod.
- Support tests on !i915 by checking if X/Y tiling modifiers are supported.
- Do not enable untested planes to prevent exhausing memory bandwidth
  and available NV12 Y planes in the rgb-switch-scaled test.
Changes since v3:
- Add a sanity test to sanity test YUV conversion paths, on all planes and pipes.
- Dynamically generate list of YUV tests through igt_format_array_fill.
Changes since v4:
- Decrease size to 64x64 to reduce test execution time even more,
  some YUV conversion routines are slow.
- Don't clear degamma/ctm, this is done in core now.
Changes since v5:
- Fix minor compile error.
